Nothing is known about this boat prior to the outbreak.
Virgil takes her to a closet with various equipment inside. As she looks through the shelves, she spots a pair of boots, which she immediately recognizes as Rick's. After a moment of shock, Michonne suddenly pins Virgil to the wall and interrogates him about where he got the boots.
Virgil takes her to a boat that washed up ashore during a big storm. Michonne frantically searches through the journals aboard, before discovering an iPhone with an engraving of her and Judith. Michonne cries tears of joy upon realizing Rick survived the explosion, but turns her attention towards Virgil a few moments later. She thinks he came to find them at Oceanside because of the engraving, despite Virgil's claims that he'd never seen it. Furious, Michonne interrogates him about what he did to Rick, but Virgil has no idea who she's talking about. After Michonne relents, Virgil offers help restore the boat to working order if the others would help him. Later, as the others pack up, Michonne informs Virgil that the others are willing to let him come along. Virgil is surprised by this, and considers it for a moment, but ultimately decides to stay on the island to be with his family.
As the boat sails north, Michonne cries over the realization that Rick might still be alive. She then radios Judith. Judith says that she'd been trying to reach Michonne. She apologizes and informs her daughter that she found three people on the island, whom she is bringing home. R.J. joins in on the call to say hello to his mother, but Judith tells him they need to use codenames for security, so R.J. chooses "Little Brave Man" as his codename, much to Michonne's delight. Michonne asks about Rosita, before switching the topic to the Whisperers. Judith informs her that the Whisperers are finished, as they eliminated most of the horde, while Alpha can't hurt them anymore. Michonne then reveals that she found something that belonged to the "Brave Man", and where he might have been recently. Choking back tears, Judith asks if Rick is still alive, but Michonne doesn't know. Judith then urges Michonne to go find Rick if she thinks he is alive. Michonne initially declines, reasoning that Judith and R.J. need her right now, but Judith insists, telling Michonne that Rick could be trying to come home and might need help. Michonne accepts her mission, and tells Judith that she will try to contact her on the walkie for as long as she can. They then say their goodbyes.
