Yep, Duela and Turner are going to be a couple by the show's finale.
Dick Grayson, Jason Todd, and Tim Drake are all being/have been used on Titans. When this show was pitched, it's doubtful that they knew Titans was ending, so WB probably embargoed those characters.
The next logical choice would have been Damian, and I can't say why they didn't use him. This was pitched long before Gunn and Safran took over the DCU, and so long before Damian was announced to be Gunn's Batman movie. They could have also used Duke, or even better, Cassandra. I'm sure no one remembers she was in the Harley Quinn movie (because that's WASN'T Cassandra, damn it!).
As for the Batcave- sure, they gave us a pretty cave. That's probably going to be shown once, since they are all on the run.
Depending on how petty the embargos are; Duke and Cass were probably booked off for the Batwheels cartoon
Cass, even if available doesn't really fit the narrative they going for with the main character I think. Duke could have though, in my opinion.
Episode 2 was not an improvement in my eyes. Steph being on the cast is the only reason I'm not dropping the show entirely right now.
Steph (batgirl/spoiler) and Harper (buebird) along with jokers daughter made this SOUND like it would be my jam... but none of those characters showed up.
A fun game me and my fiancé played was "who was this pitched for that they couldn't get?"
OUre bet so far is that JIm GOrdon and barrbra goordan got replaced by Dent and Steph
Our biggest disagreement is I think it was supposed to be a young Jason Todd, she thinks this was supposed to be a young Damian Wayne.
We do think Duella and Harper MAY have always been part of this pitch, but maybe not
We agree Carrie Kelly was most likely always the robin, but was supposed to have a real robin suit.
In the real world i would be BOTH pro registration and Pro mutant rights. Xavier and Trask were both right.
Another example of the silly H2H, no useful guns in the DC world. Old Talon would not have been problem with a modern firearm with AP rounds. Granted the kids didn't have access but just a general comment. The killer also could have shot them all easily. Just have to have a fight.
