It seems a little too late on that synergy considering it's been off the air for a long time. Yes I know about the GO series but why would they try to connect with that one when everyone who liked the original can't stand the new show? I think the current line-up is the best the Titans can do in terms of synergy since it matches most with Young Justice, the show so far has been a Titans show with the Young Justice name slapped on it.
