Tim was thrown back against the wall by the werewolf he'd thought was his friend, falling to the floor and trying to crawl away from the snarling beast standing above him. Fur bristling and teeth bared, the wolfman stalked slowly towards him. He was filled with an instinctive desire to flee, but something about the hairy monster that was approaching him held him in place. The fiery hair atop its head providing a stark contrast to the gray fur coating its body, the human clothing completely out of place on such an inhuman being, the glimmer of human understanding buried deep within those ravenous primal eyes... it shared so much with Rick, and yet was so impossibly different. Tim's mind was spinning. It couldn't be him, could it? There was no possible way... but then, the realm of possibility seemed a bit expanded by what stood before him, a creature right out of myth and legend preparing to feast on his flesh and bones.
"Rick? If that's you, you can't eat me! Come on, remember, we're friends!" Tim pleaded, but the wolfish Rick didn't show any response, instead moving closer to its next meal. Tim continued eyeing his attacker, watching the saliva drip from its mouth and onto its glimmering collar... wait, collar? Rick never wore one of those, and yet there it was, around the werewolf's neck: a shiny black rubber collar, wrapped tightly around his throat, with no visible clasp. It could be a sign that this wasn't Rick, but there were just too many similarities for that to be possible. Tim's mind rushed through the possibilities, trying to reason its way through the situation. Why else would he have that collar now, when he didn't have it before? Unless it's what caused the change!
The wolf finally descended on its meal, teeth gnashing at Tim's face. He reached for the canine's throat as it tried to bite his own, grasping at that latex collar. His fingers wrapping around it, gripping it with a confidence he rarely found within himself, he pulled with all his might. Rick's head was jerked back from the pull, the collar remaining sturdy and tight, and he starting gnashing at Tim all the more. Barely able to hold off the attack, Tim gave it one more try, this time grasping with both hands and pulling with all his might. After his greatest efforts, he finally felt the latex give, shredding apart and falling away from the werewolf's neck. Whimpering, it fell backwards, collapsing to the floor as its body violently started to change. The fur receded into the skin, the joints and bones popped back into a human configuration, and the face morphed back to Rick's familiar mug.
"What the hell just happened? I was walking, and then someone snapped something on my neck and then... whoa." Rick's memories of his short experience as a canine rushing back to him, his eyes darted to Tim. "That collar must have..."
"I saw it. Y-y-you were..."
"Yeah, I know. I was here. Look, we have to go get the others. That crazy cat bitch probably got changed by the same sort of stuff, and they aren't safe until we get rid of her. Come on!"
Acting as though nothing had happened to him, Rick grabbed Tim's wrist and pulled his friend right back down the hall they'd come from.
