I am just interested in what your favorite episode from one of your all time favorite Anime and why? Personally my favorite would have to be episode 22 of Steins;Gate mostly because of the emotional state that the episode put me in.
Especially when Okabe tells Kurisu that the only way to save Mayuri was to go back to the beta world line where Kurisu is stabbed. Not to mention Kurisu accepting her fate after seeing what the stress of seeing Mayuri being kill has done to Okabe. Then they confess their true feelings for each other and share several kisses. And the ending of the episode where Kurisu rushes into the lab to reciprocate her feelings just to be too late as Okabe already hit enter.
