Deadpool and Peter W.

The marketing for Deadpool 2 really hyped-up a brand-new superhero team, the X-Force, but the movie subverts those lofty expectations in a big by brutally killing all but one member of the team before they get a chance to do anything. However, the Merc With a Mouth manages to save one character and one character alone from a grisly fate in the movie’s post-credits scene. Why is Peter W., the extremely normal dude with no superpowers, worthy of being saved?

“I love that he just completely ignores this marquee cast that he could’ve saved of useful and wonderful superheroes, but instead went back and saved [Peter],” Ryan Reynolds explained while on the Empire Film Podcast.

It turns out that the reason why Deadpool saved Rob Delaney’s affable Peter and Peter alone had to do with a promise the Merc had made earlier in the movie.

“Well, here’s the thing though, I always felt that it was important to save Peter, just because in the helicopter before we jump, I say to him ‘I’d never let anything happen to you, sugar bear. I’m just saying this to impress the other guys,’” Reynolds said. “So, I felt like that was a promise that Wade made early on in the movie, and it was nagging him, so he went back and got Peter.”

It’s a nice little explanation that’s more emotional and satisfying than it has to be, given that saving Peter made for a really, really funny joke even without Reynolds’s backstory.

It’s unclear if Peter — or any of the dead X-Force members — will return for the X-Force movie or a possible Deadpool 3.

Deadpool 2 is now in theaters.
