Yeah, I'm not sure that's the case either. Like you said, the only one she would have targeted out of the five of us if she wanted a chance of surviving the fight is Break.

If you really do think he's innocent though, then I bet the killer used her keys to go into her room and open her profile book to frame him. He couldn't have done it himself since...blind and all.

...or maybe she just had a really big crush on him, who knows!
