[Arbitres]

I remember very clearly now one of my most favorite scenes.

Spoiler for The final blow (Episode 25):

When Guren pierced the Albion's chest plate and SEITEN lost power (So Kallen couldn't determine whether or not she actually succeeded in beating Albion).

"...I didn't get him?..." Kallen / Karen

:...No. You got me... Kallen." Suzaku

There was also this:

Spoiler for End of episode 25:

When Lelouch slowly closed his eyes and he said "I destroy worlds. And I create them... Anew." as the memories started to spurn and fade away like he did. It broke my heart after watching it again, though I do doubt his sanity I can't question his ideology any further after watching it a third time.
