I keep seeing people talking about them airing not only episodes 11 and 12 tonight, but also releasing episodes 13 & 14 online at midnight.

I did a little more searching and found that the Avatar Wiki page on the Episodes was changed to say this, as was the Wikipedia page, linking to Bryan Konietzko's tumblr page as a source.

I can't see it because my work blocks tumblr, but anyone can make a tumblr page, right?

I'm just getting my hopes up for nothing. People shouldn't spread rumors like that around without definite sources.

EDIT: Thanks to Irae giving me this link showing that while I might still be an idiot, they are releasing episodes 13 & 14 tonight at midnight.
