Look, I accept the five year time skip in that it is ample time for Garfield Logan to become Beast Boy and train enough to control them, you wouldn't want a potentially dangerous green monkey turning into a green rampaging T-rex (since he can turn into animals I am guessing he can probably turn into dinosaurs as well). Lets just say that the first season was more of the origin story for the team, I.E how it got started and who was eventually on it. This would make the current season and the next season not to require a time skip.

It is conjecture that Batgirl is Barbra Gordon, the one thing that could destroy that is different voice actors but that can be explained in many ways.
