James McAvoy has to juggle over 24 distinct personalities in M. Night Shyamalan’s “Glass,” but which member of “the Horde” is his favorite?

Kevin Wendell Crumb, a man with dozens of personalities, was originally introduced in the 2016 thriller “Split.” Audiences were delighted as McAvoy transformed into completely different characters, including Barry, Dennis, Hedwig, Mary Reynolds, and Jade. But the fan favorite has always been Patricia.

But where did she come from? Naturally, McAvoy has a whole “kinky” backstory for this captivating Brit.

“She’s pious, religious, devout, celibate, and yet constantly fantasizing about being touched,” McAvoy told Variety at the “Glass” premiere. “It gives her a little kind of kinkiness that I like and made her real fun to play. Real nice conflict within her.”

But where did Patricia originate from, and what was her purpose to serve/protect host Kevin?

“You can identify why she was born,” McAvoy explained. “Kevin was having trouble believing in a god in a world in which he was being physically and sexually abused for his entire childhood. Instead of losing that faith, that facet of his personality dissociated into a whole new person.”

The actor appears to have origin stories for all of Kevin’s personas, but there’s one that didn’t make it to the final cut, McAvoy’s impression of director Shyamalan.

“Glass” comes 19 years after the debut of the first film in Shyamalan’s comic-book trilogy, 2000’s “Unbreakable,” which introduced David Dunn (Bruce Willis) and Mr. Glass (Samuel L. Jackson). “Glass” brings all three characters together in a mental hospital, where they’re being treated (against their will) for their superhero delusions.

“Glass” hit theaters on Friday.
