Or since Beast Boy joined Young Justice in Season 2, maybe it's this encounter he has with them that inspired him to join in the first place. Also since it's Nightwing that's in Young Justice, that probably means Robin joining the team hasn't occurred yet.

Maybe the Young Justice Team they encounter is from the future, and we'll get a third appearance from Nightwing?
