Sam was here but not once was his guard down, he couldn't explain it but his gut was telling him that there was something off about this.
He knew that this was unlike Jason, Jason wasn't the kind of person to assemble an army but then again, it had been so long since he had seen him so there was no telling what kind of person he was anymore.
Sam noticed that the others barely had any sense of self, they weren't as self-aware as him making him question if they were humans.
He didn't even trust the woman before him and he had no reason not to other than his gut feeling.
If anything, this was their only chance at ending the zombies that roamed the area; however, this didn't halt the fact that they, themselves, were already infected.
Sam knew that there must be something wrong if the very thing responsible for this mess was somehow speaking to them.
