IN GA: Reed - Was he friends with Matt back around...8th to 10th grade? Because that's when Syd was with Matt, but then she left Atlanta after that, so it depends on the time frame. :D If they've known each other before Syd left GA, I'm guessing they were just the hi-and-hello type, if Reed really was a loner and kept much to himself. Syd would've been really nice to him though. :)
James O'Connor - Hahaha! Um...I think Syd would've heard Matt transforming into an ass after she left, but is still reserving judgement and would like to think he's still the same Matt she knew. James could be the one telling her otherwise? :D
Angela - Hrm. Well, I suppose they'd have to meet somewhere first because I don't think Syd would have known her before she left. Syd would be nice to her (girl is like, nice to everybody it tires me because I am not :D) but it would depend on what she'd have heard from her sister coz while old!Syd would be nice to you if you didn't like her, current!Syd just doesn't pay much attention to those stuff anymore.
Deanna - I reckon Syd got along well with Matt's siblings when they were together, but seeing as Matt totally went on the opposite when they broke up...would Deanna still like her?
IN NYC: Jenny - Heh, she sounds fun. Friends? Jenny could rant on and on about Kent to Syd, since she's Miss Nice and she'd listen. And Syd would've liked reading her articles.
Chase - If you Syd is the type of girl Chase could've gone on a date or two with, I'm offering her up to you. :D Nothing serious, turned out to be better as friends and Chase could be the one telling her to live her life more or something, as Syd can get all practical/logical (her trip through Europe could've been his idea :D).
