Age difference for Robin and Batgirl is less than that in the original comics (they changed it later when they became popular as a couple) an dis similar to the one in The Batman cartoon. I decided to go with 6 years in TT just because I prefer it in this version.
Reason for Robin's personality difference in this version is also based on stuff from early comics (kinda) and it's mostly in there cos it always bugged me how different his personality was in my favourite cartoon.

For those who don't know, I ship both dibs and robrae so that's kinda why this story has a little of both though you can interpret Robin and Raven's relationship as platonic if you like...
