Does Lucas have a bigger part to play?
By the end of Resident Evil 7, the entire Baker family is wiped out, with one exception: Lucas. Now, we know that all of the Bakers were infected with the E-Virus, and this allowed them to be mind controlled by Eveline. However, we later find out that Lucas was the only one not under Eveline’s mind control powers. Towards the end of the game, the player finds several files and notes that suggest that Lucas was working with whatever organization had created Eveline in the first place, and that they had given him some sort of vaccine to resist the mind control.
This means that Lucas had essentially become Eveline’s second caretaker after Mia, as we see him communicating with the organization and giving them regular reports about how Eveline was doing. After getting away from Lucas’ escape room, we never see him again, and Ethan ends things by defeating Eveline. This means that Lucas is still at large. Now the question is: was he evacuated by Umbrella Corp as well? Or did he manage to escape Dulvey altogether?
