Purpose

What happens when Bruce takes away Robin? - This is Damian-centric with some Batbro vibes.

His son

What if Damian was left at an orphan by Talia after a fun night with the Billionaire play boy Bruce Wayne. Talia was on a mission when she had one to many drinks with a guy at a club and had to leave the child at a orphanage in Gotham so her grandfather wouldn't force him into a life of crime.
