When Mark got the notification of the disappearances he knew where he needed to go. It wasn't just people and friends who had left, though there were a few of those, but it was pack members, and more than pack it was those that Mark knew Kitty had taken under her wing far more closely than just a fellow pack member. He knew she'd be grieving this loss more than some of the others in the past.
It never got easier being here and dealing with the way things worked, it was easy to make a life and grow comfortable in it, all the while knowing it could be taken from you at any moment.
"Kitty?" Mark called as he approached the pack house, looking for his friend and second. The losses had hit them both hard recently with Carter and now Rahne and Enid. He couldn't fix this, but he could make sure Kitty knew she wasn't alone.
