Sun is the team leader of Team SSSN. In fact his team name is pronounced "Sun" just like the way Team RWBY is pronounced "Ruby". Sun's Team consists of Himself, Scarlet, Sage, and Neptune. They were all introduced at the Vytal Festival and originally represented Haven Academy in Mistral before transferring to Vacuo's Shade Academy which is this episode where he plans to take his team there. Also Dee and Dudley are loosely based off of Alice in Wonderland's TweedleDee and TweedleDum. Also in Volume 5 during the final battle when Jaune awaken's his semblance, Jaune explains to Nora that he's not "healing" weiss, he is just amplifying her Aura which is what he is doing with Dudley. So Jaune is an Aura amplifyer which you've seen when he amplyfied Ren's aura to make Ren's semblance last longer while he shields the whole train. You'll notice in future volumes how useful Jaune's semblance is. Can't say anymore since I would be spoiling the rest of the volumes. Also keep a close eye on Adam's outfit when he's on the train. It's different from the outfit he was first introduced in the trailer. It's the outfit he changed to after volume 3. That's should give you a hint.
