I don’t know if Nebula will return beyond this, it’s possible that this is her final chapter. And if that’s the case, then I just want to say thank you to [James Gunn] for giving me such an interesting, complex, and fascinating character to play. I have enjoyed this exploration more than any other character I’ve played. That was one hell of a decade. Thanks for watching…
