Karis hates being interrupted. She was lunging for one person (he's in the way; nothing personal) when someone grabs her by the shoulder and she's yanked backwards. She turns with a wordless sanrly of anger - some jackass yelling about how they don't have to do this or some other sanctimonious bullshit - and lunges at him instead.

Her claws are out and she goes right for his face, intending on blinding him.
