A bit late, but: Hi.

I have Ashika Govendor, who is a house/yearmate. She'd probably have been a friends from first and second year. She really tries to see the best in people, so she'd make an effort from time tot ime to get him to open up. She's really quiet, and notices things others don't, so she might be suspicious.

Then Cecilia, 6th year Gryff, would be a past customer. She's generally a good girl, but overly curious. So she's definately and ex-customer, but she wouldn't.... make use of his services anymore.
