That's a letdown. Then it must be Thor Ragnarok, unless they hold off until Infinity War.

As for Nebula, simple: Recurring main villains have continued to survive and will always continue to, but recurring minor villains never last more than one film. Zola, The Other, Strucker, and Rumlow are all killed early into their second appearance.
