Wait.. that was the final?
It didn't really feel like the end of arc, and tbh the show had some far more powerful emotional scenes in earlier arcs (and not just the Disappearance stuff, the stargazing and the coat stuff were really good for awws).
However something this episode did get really well was Kyon's inability to spit it out. It felt real, and he acted like a real high scholar trying to talk about something emotionally sensitive with a girl.
The scene with Asakura knowing to do homework was funny wink wink, nod nod moment
And a final note I still can't figure out what the hell going through Haruhi's head with Kyon and Yuki. Their was a lot of scenes where her face was hidden in this episode.. and we all know what that means.
