plot with arin

Abby is gonna be all up in Arin's biz it seems xD

Bacchus and Abby are bros, so maybe she could meet Vitus and they can cry about their awful parents together (Abby has never met her dad and her moms left her to deal with her shiz on her own) and stuff like that?
Starling and Abby can attempt a spar for some fight training together at some point???
Abby was born on Obsidian beach, so there's a good chance she's gonna end up there at some point and yell at someone for taking her home, mayhaps Volty can suffer the wrath of a grumpy purple squish?

If I think of other plots I'll toss 'em up!
