Okay, so as far as we know, Lian is a normal human right? Given that as a New God, Knockout wont age and Scandal presumably has her fathers powers of immortality, how often do you think it crosses their minds that Lian's mortality is going to catch up with

It’s Liana (sorry!). :)

Scandal is long-lived, but not so ancient that losing a lover is easy. I don’t know for sure how old Knockout is.

I think they would live for the moment and love who they love, and face the consequences as they come.
