Lukas quick as a flash snatches the t-shirt away and looks down at it
Lukas: Whose is this?
He sniffs it-he WILL be able to tell by scent
Lukas puts the shirt down and walks over to Baku, eyes hardening. He gently touches the marks-he looks effin PISSED-
"Who did this to you?"
"Katsuki. WHO DID THIS?"
His hands are clenched into fists, and the blackness is starting to spread rather quickly up his fingers and arms. He's shaking, fangs bared.
