Salem is going to be having Grimm hunt down Oscar to learn how to use the relic (and for Ozpin)-

-so what if there’s a scene where they realize the Grimm are after Oscar, and he tries to go off by himself again to keep everyone safe. Jaune stops him, taking him by the shoulders in an emotional fit saying they almost lost him twice already and they aren’t going to again.

And Jaune adding he’s not letting someone run off to a fight they probably can’t win again
