Be forewarned as some mild spoilers are ahead for The Guardians of the Galaxy Holiday Special.

The Guardians’ Rocket finally got Bucky’s bionic arm. Of course, this led to fans wondering about how this happened on social media, and writer and director James Gunn was nice enough to provide the answer.
