Could Patrick Stewart be reprising his role as Professor X on Legion? According to Dan Stevens, the answer is yes!

ET's Leanne Aguilera caught up with Stevens and the rest of the Legion cast at Comic-Con in San Diego, California, on Thursday, where he revealed that he's already approached Stewart about playing his dad on the FX series!

"Oh god, Patrick Stewart takes a lot of beating and he did seem interested," Stevens said of his dream casting to have Stewart play his character, David Haller's, dad. "He seemed very unaware of the show, but I mentioned that he was my dad, and he seemed pleasantly surprised."

"This was at the supermarket?" Legion showrunner Noah Hawley asked. "Daddy!"

While fans of the X-Men comics know that David's dad is Professor X, it's something that Legion has yet to confirm. Going into season two, however, Hawley said it's "definitely" something they want to "address."

"I think we want to address that," he said. "It's normal when you learn you're adopted to want to know who your real family is. He doesn’t yet know the identity, so I think it will be a process to get there."

"There's quite a lot of explaining there, that your dad is Professor X," Stevens added.

"Because you're like, 'What does the X stand for? But yeah, we're on that path," Hawley confirmed.

Though Hawley seems to have a clear plan for the introduction of Professor X, working with Aubrey Plaza is another story.

"It was not scripted! You know, it was a choice," Stevens said of one scene where Plaza removes her pants during a David-Lenny face-off.

"We just read the script and just kind of let it inspire us and went to some weird places," added Plaza, whose Legion role was originally scripted as an older man before her meeting with Hawley. "We just made some really great choices."
