After a run-in with Slenderman, a wave of sickness blew through the guys, leaving them with high fevers. But knowing there were already people watching over Evan, and Vinnie, you knew it was best to go to Jeff. When you got there, despite being told not to come, he opened the door nd was obviously just exhausted getting out of bed, but even talking to you, slurring his words, losing focus. He was completely out of it. So obviously he wasn't "Fine" like he said.
