What is your favorite episode?

It is, without a doubt, Sonic Rainboom! Because it tells things about RD's past, and we don't get anything but their Cutie Marks as History.

Well, I would love to say all of them, but that's probably a cop-out. I'm gonna go with Read it and Weep, because after much thought I realized that it could all be interpreted as one big 'Journey of the New Brony' story.
