You know what was a wasted opportunity in the Batman Comics?
That they never had Lucius Fox’s kids be best friends or at least close friends with Bruce’s kids. You know just besides Luke some people outside of the life who could come over for dinner and who’d probably go to school with them because they’re all rich kids.
Dick at least seems to know everyone at Wayne Enterprises really well. And pre new 52 was the same age as Lucius’s son Timmy. Pre reboot there was also Tiffany who could have played an older sort of cousin role. And now Dick is probably similar in age to Timmy still even though I think he’s only appeared once. There is no reason why Dick who probably spent a lot of time at WE as a kid couldn’t hang out with Timmy. Also to note they both became estranged from their fathers around the same time. More bonding.
Jason Todd should have been about the same age as Lucas Fox. They could have been good friends before Jason died. Maybe angry Jason Todd reminded Luke of how angry Timmy used to be and he didn’t want Jason to run off like his brother did.
Cass could know Tamara well as a friend outside of the family. And pre reboot she would have been younger than Tiff and could have had another family friend older sister figure.
Tim at seventeen is probably around the same age as Tamara. He knows Luke well enough but could have interacted with Tam some more. Plus if he ever met Timmy they’d immediately latch onto the same name jokes.
Tiff has been made Lucius’s youngest child in reboot and I honestly have no idea how old she’s supposed to be. It varies from like ten to looking like she’s four. But they also seemed to forget they killed Tam so whatever. If she’s about ten that’s perfect another non super friend for Damian and she’s really smart so he shouldn’t be too annoyed by her. Or if she’s younger like four Damian could have adventures in babysitting.
I just wish they’d use the Fox family some more.
