I think that was it. He mentioned he feels like he'll pass out too, then falls into despair. From what I gather, the lights weren't really about "giving people second chances", but that it represents happiness, "making people's wishes come true".
Tomoya just imagined a hypothetical scenario/dreamed about what would have happened if Nagisa died (and Ushio too, I guess). It also explains why he can keep flashing back to whether he should have met Nagisa or not. That said though, being a dream and all, I believe the conclusion he's come to within himself is that he doesn't regret meeting Nagisa after all.
The first part of this episode was great. There wasn't any witty plot twist, and to be honest it invoked almost zero emotion. One thing it did do, and did very well IMO, is provide closure. Wrapping everything up, you find out exactly what happened, where everybody's at (1), and a sequence showing the happy family trio we've all been hoping for. The sense of "completeness" is there, despite the slight feeling of being cheated.
(1)Except Tomoyo - she's at the beach? Still looking hot as always though, so I'm hoping for a Ep24 Tomoyo After special again
Tomoya x Ushio = Robot x girl made sense enough.
I still don't get why he's in both worlds, or why Ushio has to remain "there", but those scenes always seemed so mysterious (and not having much to do with the story anyway) and it really doesn't matter.
The Fuuko bit however......wasn't so good. It wasn't all that funny, and I really don't give too much about her. She made her comeback a week or two ago, and that's enough. In that regard, it was half an episode wasted.
While I'm not wowwed by this episode or anything, I certainly feel satisfied with it as the official ending ep since it did just that.
