When you asked me what was saddest for me when I thought it was gone—and anybody at Marvel can tell you—it’s this very strange and attached relationship to Rocket. Rocket is me, he really is, even if that sounds narcissistic. Groot is like my dog. I love Groot in a completely different way. I relate to Rocket and I feel compassion for Rocket, but I also feel like his story has not been completed. He has an arc that started in the first movie, continued into the second and goes through Infinity War and Endgame, and then I was set to really finish that arc in Guardians 3. That was a big loss to me—not being able to finish that story—though I was comforted by the fact that they were still planning to use my script.
