FWIW, my current imagined ending is for Ruby to have to use up all her aura to activate a Giant Bigass Super Planetary Shield that seals the Grimm's nether dimension off from the world. It was a volunteer-only mission because the Dust-mages (led by Weiss) who had designed it were explicitly clear that the person who triggers it would be killed instantly. But Jaune has a feeling that his unusually-powerful aura might be able to survive the drain. However, at the last minute, Ruby blindsides him, knocks him down and steps towards the device.

RUBY: "Jaune, the hardest thing to do in this world is to live in it, to keep on living when you have nothing and no-one left, not even hope.  But I know you, Jaune Arc; I know that you are strong, even stronger than you think, which is why you have to live.  For Yang, Weiss, Blake... for all of them.  You're going to have to be their strength from now on. If you can't live for them... if you can't live for yourself... then live for me.  Mom was right, you see... Tell the headmaster that I understand now! Death is the gift of all the women in my bloodline... to die so that the rest of the world might live.  Good-bye, Jauney. I love you."

Then she steps into the blazing fountain of energy flowing up into the shield projector and we get a 'space magic' moment to rival the climax of Mass Effect 3.

No healer could bring the victim back because of the drain on their own auras... But Jaune has an unusually powerful aura... Cue a "True Love's Kiss" moment...
