I can’t post a clip right now, but it goes:
Luke calls back to a knock on the door with “go AWAY.”
Chewie’s grenade blows the door against the far wall, and could have easily killed Luke.
Chewie steps in, roaring angrily.
Luke asks “Chewie, what are you doing here?”
Chewie growls and speaks in a medium tone.”
Luke asks “The Falcon?” A bear passes. “Where’s Han?”
