Honestly, I´d love to see Oscar and Qrow train in the next volume.I mean, Qrow´s semblance would bring bad luck to Oscar, and since Oscar is Ozpin, this would mean that Ruby and co. would show up and ask why Oscar has Ozpin´s cane. I mean, I´d guess Ozpin would like to keep his immortality a secret from as many people as possible, so having someone ask unwanted questions would be really bad luck...In my headcanon, Oscar just tells team RNJR that he inherited it, and then just sais that his relationship to Ozpin is complicated.Another idea is a scrapped fanfiction idea of mine, in which my OCs, Team ANST, meet Team RNJR by coincidence, since they were on the way to Mistral themselves for various reasons.Argent Star: Stick with his team.Niob Bolt: Meet some "friends".Sirena Blue: See the world.Talia Star: Someone hacked the Amity Colosseum during the last Vytal Tournament, and Cinder was the first to speak. Talia isn´t as stupid as everyone thinks she is, and since Cinder mentioned that she was from Mistral, Talia is there to give Cinder a piece of her mind.In this fanfiction, Team ANST would train Oscar instead of Qrow, because Qrow´s semblance would only cause unwanted trouble. Oscar would be given the choice of who he wants to fight first, and despite Ozpin´s warning, Oscar picks Talia, since she is the youngest of the team. This little mistake does have its good sides, though: Now you need more force than a sledgehammer to break through Oscar´s defense, and he can block mashine gun fire from up to 5 different directions at the same time.Next, Oscar would pick Sirena as sparring partner, mostly because her trident´s staff-like shape is similar to that of his cane. During the fight, Sirena would mention that this cane has a long history, and then explain to Oscar that she is from an under water kingdom and that his cane once belonged to a bodyguard of the royal family. After his death, it was stolen, never to be seen again. Oscar would then take the bandages off his neck, revealing a pair of gills he had been hiding for as long as he can remember, and ask Sirena if she could show him where this kingdom is (and yes, he is a faunus in this fanfiction).Argent would then teach Oscar one of the most important lessons ever: Seeing without seeing.Niob would´ve gone missing, but his team knows that he´ll show up again eventually, so that´s cool.Also, sorry for the wall of text and thanks for reading.
