https://www.youtube.com/watch?v=ZlZO2qQOaZ0The "But although, we all know who he will end up with later" line makes me think that they are still going to made the immature beast boy to be with raven in the next or later films.
Which is kind of sad consider they have been doing and building the robin( Damian) and Raven relationship more and they are kind of cute the more you see them.
Are they going to do some strangle relation of the three and the their romance happen because Raven want to feel more emotion so she did some tricks on robin's mind thing like they did back in the comic(Only this time is Damian instead of Dick )?
That's the only way i see they can push the Beastboy romance.
