Jack was probably aware Lucas had problems since they took him to doctors before, and the murders didn't start until after Eveline arrived.

Eveline being killed doesn't stop the mold from existing, thus Lucas is still infected. You may be confusing him being 'uninfected' with having taken the serum to stop Eveline's influence. Lucas was never cured of the mold infection. The implication was Lucas' friend doesn't exist, it was in his head. You're right some the VHS stuff doesn't make sense due to physics, but that wouldn't be a plothole and they're meant to be gameplay and aesthetic thing. For what reason would the cop call for backup? There wasn't any confirmed danger. This game literally makes no sense at all. It goes so far beyond plot armor and canon in so many cases it makes my head spin. None of this shit makes any sense what so ever. How where they going to doctors appointments after being infected? And how did they not infect everyone they came in contact with? And why wouldn't Eveline go to those appointments with them to infect as many people as possible? How come Zoe is still infected and controlled by Eveline after receiving the serum, and Mia still ends up at the wrecked ship even if you save Zoe? And why is Lucas infected, then he actually isn't, but then he still is? And why is he after Eveline has been killed? How does Jack not know his son was a psychopath way before Eveline arrived? And in the daughters tape, Eveline infection happens immediately, to the point where the Baker's would not be able to go out in public without drawing the attention of the entire USA. Why didn't that cop call for back up? And how did he access the property when Ethan had to be dragged through by Jack to get in? Why is everything being recorded and saved on VHS tapes around the house in 2017, and how are characters like Clancy carrying them around while subjected to Lucas's torture? In fact how did Clancy's tape survive an explosion and a fire? How is it that no one discovered a decomposing body of a neighborhood friend in Lucas's attic? In fact, where did that friend even come from? There doesn't seem to be much of a neighborhood.

From engineers designing entire cities to have weird, archaic puzzels, and zombies infecting through bites, except for the main characters but Jesus Resident Evil 7 takes it to the next level. I know the plots of resident evil aren't always the strong points.

Not a hero re7 plot
