Derek is on his way back from picking up some snacks when he sees Tara approaching. He hasn't seen much of her since they met, and he plans on just giving her a friendly nod as he passes, but she gets closer and the sharp tang of blood hits his nose just before he sees the streaks of it all over her, on the dog even. She looks a little shell-shocked, like she doesn't even know where she is, and Derek frowns.

"Whoa, Tara, hey." He steps in front of her to stop her path and inhales deeply as he looks her over. The blood isn't fresh and he doesn't smell any open wounds, but it's definitely hers. The dog whines, ears dropping back, and Derek turns to reach his fingers out, calming the dog before he looks back at Tara again.

"You don't look so hot. Are you hurt?" He doesn't think there's anything physically wrong with her, but the blood had to come from somewhere. "Hey, what happened?"
