Which is complete bullshit for anyone outside of the Slytherin house I might add. No one has reasonable grounds to suspect her of anything, other than her fellow Slytherins. She's been perfectly nice to everyone - and the other Slytherins, they're not going to say anything about it. The select few who might, Verlin and Isaak, they'd be in the minority and aren't going to get very far with accusing her of anything.
