Aleks: Probably nothing much there. She's hot and has a great body but not exactly his type tbh. But he's a nice dude so he'll probably get along with her anyway? Oh! He's childhood buds with Michelle so I guess he'd be like her big sister's friend in her eyes more than anything. So actually he would know Amelia, sort of a little sister type then. So ignore what I said earlier about nothing much XD There! He's meesh's friend and might view her more as a younger sis/cousin than anything.
Cara: SHIELD agent. Same age but is like...polar opposite to Amelia. Like seriously I don't think you could make them as opposite if you tried XD Though they both do compartmentalize things. She's impressively unconcerned with appearance and vanity though. They probably had a lot of classes back in high school together. And she's good friends with Billy so if Amelia knows Billy, she's probably met Cara. I have NO idea if they'd get along. On one hand they're like polar opposites, on the other...well Cara gets along with Billy just fine so...XD You never know.
Cliff: Teenager, got nothing for him. Will send him to X-Factor for career day and if she's around he will NOT look at her. Because she's like an overwhelming type of hot and he'd rather not stare, so he'd go in the complete opposite direction and just avoid looking at her at all.
Peggy: They've probably run into each other a few times at least on the talk show/publicity circuit but I don't think Peg would like hang out with her in public much, but if they were on the same talk show they'd probably hit it off (Peg can be pretty charming and friendly). Though Peg really avoids any marketing things that are too sex appeal (she's trying to keep to things that if young girls want to follow, they can) so they wouldn't overlap on who gets endorsements/models for stuff, etc (Peg models more in a celebrity capacity rather than as a model model).
