When Kale stepped in, a few things were apparent. First, Teddy was just in the next room and could definitely see her. The startled expression he made as he looked up at her was evidence enough of that. Second, either the white fang has seriously upped the quality of it's break room, or this place is a bar. Namely, the back room of Mac's Time-out. Third, and most crucial, Teddy was kneeling down and putting on boots, his white fang mask on the floor next to him.
Teddy's heart stopped for a second as someone came into the room behind him. Someone was following him. Was it the cops? Was it someone looking to mug him? Was it someone from the Fang? Did he do something wrong? All of these thoughts flowed through his mind before he even looked up at her. In the dimly lit room, he couldn't tell her face under these circumstances, let alone her having the mask. He fell backwards, leaving the boot he was trying to tie on behind as he desperately scooted away from this mystery assailant.
