Samurai Jack - Sums up my feelings on this episode

Obligatory

Yeah, look, you're allowed not to like it, OP. But this doesn't make this any less whiny.

You WANTED a 'father-daughter' relationship, even though it was never owed to you or suggested by anyone but people on the internet. You didn't get it, so maybe learn to live with it. What happened in this episode in no way negated any of the things you expected.
