I think so, because Alex's appearance has changed a lot and she told Travis what happened to her and Jake. The last time we saw them they were given water and food, how could they run out of supplies only after a day?
Also, the Abigail can't travel so fast like that when in "Ouroboros" the group was still near Catrina Island but in "Blood in the Streets", after only one night they had come to Mexico, that's almost impossible.
So I think a week or at least a couple days had passed since the events in "Ouroboros". Do you guys think so?
