She thought about going back to her dorm, or catching a bus and going home—but neither place held much of what she wanted at the moment. Although, she wasn’t sure what she wanted, just that those places didn’t have it. Which is what lead her here, outside of his door and just waiting. She started to bite her lower lip out of nervous habit and hissed when teeth collided with torn skin. And that just brought to the forefront of her mind exactly what she looked like. Her hand and wrist were definitely sprained, and the knuckles were bloody and bruised, and there was a brilliant matching bruise on her cheek.
And other bruises that she wasn’t going to talk about yet. Especially since they were all hidden by clothing. (Even if some of the clothing got torn in the fight. Assholes.) Hesitantly, Carol raised her hand and used the side of her fist to knock on the door. At least she remembered not to knock normally. That would’ve sucked.
Now, she just had to wait.

When Llewyn tears himself away from grading papers to answer the door, the last thing he expects to see standing behind it is a bruised and battered Carol Danvers. It makes something angry and frightening bubble up inside his chest, and he either wants to stamp it out immediately or chase down the person (or people) that caused her harm.
“Carol,” he starts, stuck between blinding fury and crippling guilt, fear, and – and a lot of other not-so-happy emotions. He shouldn’t be feeling these kinds of things for a student, but it’s far too late to turn back now. He’s in deep. And right now, he doesn’t give a shit about it. He’s got some information to gather and potentially a few asses to kick.
Lou moves aside and opens the door the rest of the way. “Come in and tell me what the fuck happened to you.”
