I've never gotten to ply it before so I'm excited!
Caden is totally welcome into Elliot and Xo's high school girl squad :D Xo's big into girl squads. And yes as far as Xo's concerned the other half of Olly's genertic material doesn't matter. And I would be up with them keeping in touch or reconnecting when she showed back up in town, whichever you'd think would be more fun :D
Gregory's super helpful in general so he'd be more than happy to help. And George will try and get Reiner to chase tennis balls with him cause they're the greatest thing ever inventeeeeeeed.
