Hope and Iris receive secret messages from their father from where he's working at the Civic Republic Research Facility stating that there's and his safety is not assured and that its gone bad. After being given a coded map to the research facility's location in New York by Lieutenant Colonel Elizabeth Kublek, Hope, Iris, Elton and Silas set out to find and help him.

In flashback to the Night the Sky Fell, Leo and Kari run through the chaos with their daughters, trying desperately to get to safety. However, after a plane full of walkers crashes, Iris freezes and she and Leo get separated from Kari and Hope.

"The Tyger and the Lamb"

While cleaning up Leo's lab, Silas finds a picture of Leo with his daughters.

"The Wrong End of a Telescope"

In a flashback, Hope angrily confronts Leo for not showing up in Principal Kallenbach's office despite Hope waiting for him all day. Hope is angry when Leo's response makes it clear that he forgot and Leo explains that he was going to go between classes, but then he came up with the exact right phrase for the start of the Advanced Immunology textbook preface, the one that was giving him all of the trouble. As a result, he forgot about the meeting. After that, Leo had another class and then he thought that if she sat there all day, Hope might think twice before setting off stink bombs to try to get a day off of school. He had then gotten distracted by wondering if it was just a product of the background processes of his brain which had made Leo forget again until right now.

Leo asks Hope what's going on with her since this is getting to be a regular thing with her, but Hope reveals that they weren't just stink bombs but time-release stink bombs that had taken two weeks to perfect. Leo returns to his work without a word and Hope accuses him of kicking himself some days for "picking a dud like me" and that he had at least done well with picking Iris. Getting up, Leo tells her daughter that the adoption agency had told Leo and her mother that Hope and Iris had shared a crib and that they were inseparable, bonded before the Bennett’s had ever met them. From the moment that Leo and Kari had laid eyes on them both, they had wanted to protect Hope and Iris and they knew that if they couldn't, that Hope and Iris would protect each other instead. Hope has done well with Iris and vice versa and Leo promises Hope that he has never wished for another Iris and he loves Hope unconditionally, but he hates that Hope doesn't see herself the way that her father does because she is exceptional.Hope leaves with the excuse of helping Iris before her sister burns dinner, but Leo stops her, asking about the composition of her stink bombs. Hope corrects Leo's assumption and while he admits that it wasn't what he would've done, it's not bad. Smiling, Hope leaves without another word.

In another flashback, Leo apologizes to Hope as he gathers things from his office, but tells her that he has to go. Hope argues against her father putting himself in danger who knows where for people that he doesn't even know, but Leo states that the CRM are good people, or they seem to be at least. The Civic Republic shares the same goals as the Campus Colony and they need to trust them. Hope points out that good people would tell you where they are taking you and she accuses her father of not seeing things clearly. However, Leo trusts his brain and his brain is telling Leo that the clear thing is to trust the CRM. Leo feels that any chance he gets to teach emerging minds to train more people in the things that they all need to know is the only way forward. Hope insists that the world that her father is trying to save is over, but Leo tells her that it's not the end because if it was the end, it would be easy, but it's not. Leo is sure that humanity still has a shot and he intends to take it.

Tearfully, Hope promises to be better and to stop being a screw up, but Leo reassures his daughter that he isn't going on this trip because of her and that Hope isn't a screw up. However, Hope isn't convinced that she's not a screw up, but Leo tells Hope that she's just frustrated and it's not her fault. Leo has intended to talk to Hope about a lot of things for a long time and he promises that they will talk about them when he gets back. While it's big stuff that he needs to say, Leo promises that it's not bad stuff. Leo brings up how the CRM has said that they can't communicate because the CRM doesn't allow any messages to go in or out before revealing that he's figured out a way around it using a tweak on some old technology. Leo will be sharing it with the Omaha Council when he gets back, but not until then. Leo will show this device to Hope, Iris and Felix, stating that Felix is family too. Hope is impressed that her father has made a communications device and he jokes that he can be bad too. Leo promises Hope that it's gonna be fine and that he loves her more than she'll ever know and the two hug.

He later appears in a picture on Dr. Lyla Belshaw's desk alongside Lyla, Samuel Abbot and another scientist.

"The Deepest Cut"

In a flashback, Felix and Will eat dinner with Hope, Iris and Leo. Felix brings up how the CRM is adding a second person to join Romano on Leo's security detail which Leo confirms. While Felix had thought that it might be Dwyer, he had asked and she said that it wasn't her. Felix is surprised that Leo isn't just asking who he wants before Will admits that the second person is him. Felix is shocked and Leo quickly asks Hope and Iris to get dessert ready so that the three adults can talk alone. Felix asks why Leo would do this, but Will explains that it's not Leo's fault as Will had asked to be the one to go. Leo explains that Will had told him that this is what Felix really wanted but was too afraid to ask. Leo promises Felix that he's only ever wanted what's best for him and leaves to go check on Hope and Iris in order to give Felix and Will time alone together.

In another flashback, Iris asks Felix if the transport to Omaha is ready to go and he confirms it, stating that a CRM helicopter will pick them up there. Felix asks where Hope is, but Iris tells her that she's not coming. Leo enters and explains that Hope is still angry that he's leaving. Iris leaves to get the rest of Leo's bags, leaving Felix, Will and Leo alone. Felix apologizes to Leo about Hope and Leo tells him that he keeps reminding himself that anger is just the soul's attempt to avoid sadness and that some people can't bear to say goodbye. Leo warns Felix that you can't outrun pain which will just sit patiently waiting for you to get too tired to run. Leo then leaves Felix and Will alone to say goodbye.

"In This Life"

In a flashback, Leo and Kari are introduced to their daughter Iris for the first time by an adoption agent. Leo notices Iris sharing a crib with another baby and the agent explains that the baby is Hope and that she and Iris have been looking out for each other from the moment that they met. Leo and Kari share a smile as they decide to adopt both girls.

In another flashback, a distracted Leo sits at dinner with Lyla Belshaw. Leo apologizes for being so scatterbrained and admits that he just thinking about the girls. Lyla reassures Leo that he doesn't have to apologize for missing his daughters and Leo states that he gets lost thinking about what they're doing. Lyla recognizes just how much Leo loves his daughter and tells him that that is just one of the things that she loves about him. Lyla suggests that Leo pretend that he's with Hope and Iris now and asks what he would be doing with them on a Tuesday night at 8:30. After thinking about it for a moment, Leo is sure that Iris is helping someone or working on her assignment from school while he's sure that Hope is with friends getting into some kind of trouble.

Later, Lyla gets up to get more food and Leo asks her if she had ever heard from Dr. Samuel Abbott since he went back to Portland. After a moment's hesitation, Lyla claims not to have heard a word from him, stating that they were sad to lose him. Leo comments on how sudden Samuel's departure was since before Samuel left, he wouldn't stop talking about how much he loved it at the research facility and the opportunity to mold the best young scientific minds. Lyla claims that Samuel had gotten word that his sister wasn't well and quickly changes the subject by giving Leo his next helping of lentils. Lyla realizes from Leo's reaction that her cooking really is terrible, but he promises that she's still incredible. The two kiss, promise each other no more lies and laugh.

After dinner, Leo and Lyla share a glass of wine and Leo suggests that Hope might want to be a vintner, having found a few books on winemaking in her room before he left which Leo realizes could just be Hope wanting to drink booze. Leo begins to explain how he knew how brilliant Hope really is.

In another flashback, Leo walks into the study to find processor chips and circuitry everywhere with a 6-year-old Hope working on dismantling a computer. While Leo thinks at first that Hope is just being disruptive to try to get his attention, he was wrong. Hope was just doing what Hope does and being curious. When Leo walks in the next day, he discovers that Hope had put the whole computer back together by herself. Leo later tells Kari that this isn't something that normal kids do and Hope is extraordinary while Leo and Kari watch their daughters playing together.

In the present, at dinner, Lyla is distracted and Leo asks what's on her mind. However, Lyla hesitates and tells Leo that it's nothing. Leo opens up to Lyla, telling her that this place is important to them both and the Civic Republic's civilian government is doing great things, but Leo has his suspicions about the military. Will's scouting expedition with the CRM was due back a few days ago and although Lyla tries to dismiss it, Leo questions how Lyla can be sure that Samuel went to visit a sister and he thinks it's possible that they are being lied to. Leo has an idea of how they can know for certain, but he needs Lyla's help.
