Okay, we all know that Aqualad is going to be in the episode "Pirates". But it looks like he will return again in another episode AFTER pirates.
When looking on the cast's twitter, I found a photo of the cast with both Ashley Johnson (Terra) and Wil Wheaton (Aqualad) at the filming session with them. Then Ripto22475 pointed out to me that Ashley Johnson commented on the tweet, "Terra and Aqualad are BaaaAAAAaack!
Here is a link to the tweet: https://twitter.com/tarastrong/status/459766149085798400/photo/1
So it's safe to conclude that Terra and Aqualad will return in the same episode later on in the season, sometime after Pirates.
Confirmed content ends here! Now here's where the guessing begins:
My prediction is that Raven will end up with Aqualad (not in Pirates, but later on in the series), and Beast Boy will end up with Terra. My guess is something like Beast Boy will end up with Terra, so Raven will go out with Aqualad again, or vice-versa. But in the end, Beast Boy and Raven will either admit their feelings and get together, or the story will drag on into another episode (lol). Any other thoughts/predictions?
