I have this thing for dramatism, so I realy like to see dramatic scenes, especially those that leave you heart-broken for a while, but it actualy ends well. But the feeling remains for the whole of the episode, that's the episodes I absolutely can't miss.
Sure, one could say it's just me wishing for some character to be harmed or seen suffering, but actually, I simply have this strange preference for those parts where it does suffer but deserves it, and it ends up well. That's a valuable lesson for anyone.
