Siobhan's Links
Alistaire is Shiv's disaster of a younger brother. He disappeared and ignored everyone's texts for months, and there he was on TV frolicking as a supervillain... she tried to tell him he could just come out, but he did... that instead. Whatever, that's his choice, she's just glad he's okay. She's the one to reach out, and it's well-received, and now they text or call somewhat regularly, though she's pretty busy.
Siobhan is Alistaire's incredibly competent and accomplished and normal older sister. She was the only one to really make an effort to reconnect with him, and he appreciates her for it, though he found it surprising -- didn't normal people like her, busy getting straight A's and gainful employment, try not to waste too much valuable time looking down their noses at freaks like him? He realizes that was a harsh and unfounded expectation to jump to about his own sister who was, credit where credit's due, always there for him growing up, and now they're on good terms.
That guy her brother hangs out with. Also the Gunslinger. She thinks the cowboy LARPing is a little juvenile, as are all his interactions with her brother (so cringe to watch...) and she cannot believe she and he are the same age. That being said, she has nothing against the guy; she honestly expected Alistaire's best friend to be equally insufferable and at least 60% as bizarre, but Charlie is pretty chill. Sometimes they both have the same snarky teasing comeback to something Alistaire's said.
Charlie's interactions with Alistaire show her a side of her brother she never knew existed. It's often jarring for her to be reminded just how much he's changed... and Alistaire seems slightly on edge whenever Shiv and Charlie interact. They were only introduced in the first place by accident, and she wonders when, if ever, he had been planning to let them meet.
charlie didn't know shiv existed until she walked in and discovered his secret identity, which makes things a little awkward between them at first. she's so different from her brother (ie normal) that he has a hard time figuring out what to expect from her (the way anyone would be after finding out about your best friend's secret older sibling who you happen to be the exact same age as), but he thinks she's pretty alright. he likes that he can complain about alistaire to her because she Gets It in a way that other people don't. at the same time, they are often out of sync in that they see completely different sides of alistaire; listening to shiv talk about alistaire makes him wonder what he's not seeing.
