I've played Minecraft Story Mode a lot and finally completed Episode 4. I'm sure I didn't miss anything else. One da I was watching a Google Play commercial when I saw a scene when Jesse, Axel, and Rueben are having a snowball fight. I've never seen this before, and I know it's not going to be in Episode 5 since

Reuben dies.

I think this video explains it right in 0:07 of this video:

Has there ever been this scene before? I played the game all over again and there was still no scene of this snowball fight.

Update: Found some images from here:
