In memory and little mementos like his armor/coat and sash, yeah. Don't get me wrong, I think it was a good thing that they killed her off in order to let Jaune grow as a person and fighter. I just don't see her dead forever, I mean in the RvB universe they killed Church off 4 times and he came back every time. I just think that this is a prominent possibility that would make for a welcomed surprise and give a darker narrative to the story, esp in Jaune and Ruby's case.
