>>122585902DC decided in 2018 that they wanted to kick Damian out of the Robin mantle, probably to make him into a villain, so they put Adam Glass on Teen Titans to assassinate his character for two years.
Then a lot of people in editorial got fired, including Dan Didio, lots of plans got scrapped and DC's direction for Damian was loathed by fans, so when Joshua Williamson made his pitch for a Robin book that would put Damian back on the path of a hero last August DC gave him the job.
