Rocket will surely have more speaking roles at one point, whether it's the TV show, the comic or in the legacy game (where they'll be having cut scenes - YAY!)

They really wanted that kiss scene at the end of season 1 and couldnt leave aqualad as a 3rd (7th) wheel lol.

I know in legacy, both Rocket and Zatanna have not left the team yet, so during the end of the 5 year gap, they are still in the team before the major mission that is the main part in legacy (which is in the 4th year if i remember correctly).
