After seeing James Gunn’s Guardians of the Galaxy, audiences were left with a pretty big question: “Who is Peter Quill’s father?” (Second, of course, to, “Why do you let him lick you like that?”) Gunn isn’t saying who Quill’s dad is, but he today tells Empire who he isn’t.

“It’s definitely not the character who it is in the comics,” says Gunn, knocking Spartoi emperor J’son out of the running. “I’ll say that much… There have been a lot of documents passed around about who Peter Quill’s father is between a select two or three of us. That’s been part of the plan since the beginning, that’s something I had to work out before we shot the screenplay. We wanted to make sure Yondu’s place in everything made sense and it does, so it’s all very specific stuff.”

Gunn also updates on whether or not we’ll see Thanos in Guardians of the Galaxy 2.

“He will show up if he helps our story,” says Gunn, “and he will not show up at all if not. Thanos is not the most important thing in ‘Guardians 2,’ that’s for damn sure. There’s the Guardians themselves and other threats the Guardians are going to be facing that are not Thanos.”

Guardians of the Galaxy 2 is set to hit theaters on July 28, 2017.
