Well we already discussed Crisis with Alice, now she despises Jeremy, the careless optimist boy makes her want to slit his throat, so I'm seeing a very funny interaction here
Now Ginny, Ginny is pretty canon, confused, deep, radical and such, she is defo liking Alice, in fact she wants to know more of Neville's past and all, so she is very interested in her.
She generally likes Jeremy but don't take him too seriously
