Astoria - Grumpy? Astoria?? I don't believe you. :p Hermione doesn't hate her, but nor does she like her. James might want to pick on her. Ted will be nice and Zach will... beeee Zach.
Alicia - Hermione knows and likes her. James doesn't know her but will like her. Same with Ted. Zach knows about her and doesn't gaf. I am planning on picking up Fred again though... He gives lots of fucks! <3
Peter - James has feelings about Peter. None of them are very clear or easy to handle. At least he's not quite at Sirius levels of "I wanna kill him"...? Ted is the most likely to be understanding of him. Hermione hates him OH so much.
Dorcas - James knows her! None of the others do probably, but Ted and Hermione will both be nice (particularly Ted, who wants to be friends). Zach will not.
