The whole last 10 eps (from when Realize kicks in and onward) was truly orgasmic, I felt like the first 40 or so episodes were just build-up for the most fantastic episode romp I've ever seen. Other than that, the death of Nichol, Kira showing up in Freedom and helping Athrun versus the druggies, the death of Uzumi (cagalli's father)... that episode was so DAMN good. That music (akatsuki no kuruma) + the fact that it was revealed that Kira & Cagalli were siblings... the timing of that moment was so ingenious, and then he died too... damn, good days.

Oh and I like when Yzak shot down that carrier full of annoying kids too. I hate kids.
