Unfortunately, subtitle's are not available but I believe you can get the gist of this even without them. If you didn't, see the synopsis for background information as well.
SYNOPSIS:
Darth Vader's wife Annukka has left him - for Mr Spock. Darth is crashing at Chewie's place. Chewie is Darth's teenage daughter's boyfriend. Chewie and the daughter are taking a break from their relationship.
Darth believes he and his wife who ran off with Mr Spock a couple of weeks earlier has prepared Christmas for everyone believing that he and his wife must "act like adults" for their daughter's sake.
After Annukka confesses her love for Spock he reveals that there has been a misunderstanding and that he's not at all in love with Annukka because, as a Vulcan, he's totally incapable of feelings. Annukka is supremely offended and tells Spock to take a hike. Darth and Spock agree to go bowling in the near future. Spock says goodbye and tells everyone that, to be perfectly honest, this entire episode has left him totally cold, and leaves. Darth enjoys his popcorn watching the drama unfold. A woman scorned, Annukka ruins Darth's suit. Chewie's moving speech saves the Christmas for everyone.
