"Guardians of the Galaxy 2" actor Sean Gunn has dropped some details about the upcoming film.

According to Sean, who played Kraglin and was a stand-in for Rocket Racoon and Thanos, one thing to watch out for in the sequel is Rocket Raccoon's personal and emotional journey.

There was a glimpse of Rocket's emotions in the first film, when he lashed out after Drax (Dave Bautista) called him vermin and then cried as he related that he was "torn apart and put back together over and over and turned into some little monster." He was also emotional when Groot (Vin Diesel) sacrificed himself for the group. Beneath a gun-toting badass persona lies a vulnerable animal who has been through a lot and that side may be dealt with in the upcoming sequel.

The Bradley Cooper-voiced raccoon is a product of an experiment, though the first film didn't elaborate on how he came to be. In the comics, however, the fictional superhero named after a Beatles song was a genetically manipulated animal companion from the planet Halfworld. Rocket and his first mate in the comics, Wal Rus, were given human-like qualities, such as intelligence and the ability to walk on two legs, to take care of mentally ill inmates.

In an interview with ComicBookMovie.com, Sean revealed that Rocket's personal issues stem from his doubts on whether he belongs to this family of misfits, thieves and former assassins.

"Oh yeah! Rocket has a lot of great stuff to do in this movie," the actor said. "There are a few relationships that are central to the theme of the movie and that really go towards keeping a family, and Rocket has the same sort of crisis of faith about whether or not he belongs in this family."

The actor's statement comes as fans of the film series are fixated on the first film, following "Guardians of the Galaxy" director James Gunn's comment that they have yet to find the final Easter egg in it. Sean and James Gunn are brothers.

"Guardians of the Galaxy Vol. 2" will be released on May 5, 2017.
