Yeah my writing process is about 75% uncertainty. I don't know where I'm going just that's somewhere?

My au is a Supergirl CW story. Basically we meet Mon-El on Daxam before his star system became uninhabitable, and he meets Kara. I am fretting a bit about making him too unlikeable since it's a step back from the latter half of the last season, but his pre-series flaws are pretty clearly stated canon? Similar problem happening with Kryptonian Kara tbh so I hope I'm walking the line okay.
