Man, it's Sophie's Choice in here, Kori or Babs, the two best ships for Dick.

Hmmm... I think I see him more likely to end up with Babs in the long term after a relationship with Kori during his Titans days, when he was away from Gotham. Dick's not super organised and Kori has alien biology so maybe that resulted in a child? You could make Nightstar a good few years older than the Grayson/Gordon child to represent that.

If Superman and Batman revealed themselves in 2017, that would be around when the Flying Graysons died, making Dick somewhere between 45-50. He hasn't been in the Titans since he was, well, a teen, so that would make Nightstar around 30?
