Aww, thank you! I shall feed on your praise and it will keep my little tummy warm for days to come :)
As to your questions:
Chloe: A big part of her storyline going forward will be whether you can (or should) undo what you did to her. And, if you don't, what can be done to silence, train or convince the remaining piece of Chloe that's still in there.
Quirks: They're not all unlockable, currently, but most of them will be available before the end of Act Two. I'll be trying to get as many of them plugged in as quickly as possible over the next few weeks.
Hope that answers your questions, and thanks for the kind words! I appreciate it :)
