She and Gwen are main girls, they will have more development.
But most likely in act 3.
From what Arc has said before, their stories would revolve around figuring out if you can (or even want) to revert what you did to them.
But more than that is still a mystery.
Will Chloe get more "roommates"?
How the hell is Gwen that strong?
¯\_(ツ)_/¯
