The New York Post has a piece where the plot outline for episode 1 of season 2 has been translated into Dothraki (I assume by David).
http://www.nypost.com/p/blogs/tvblog/game_of_thrones_plotline_translated_QrennHPZw254N9WqVDSu2LThere are several new words that I don't recognize so this will be a good text to go through to pick out all the details.

English
As Robb Stark (Richard Madden) and his northern army continue the war against the Lannisters, Tyrion (Peter Dinklage) arrives in King’s Landing to counsel Joffrey (Jack Gleeson) and convince him to put a lid on his self-indulgence. On the island of Dragonstone, Stannis Baratheon (Stephen Dillane) plots an invasion to claim his late brother’s throne. He also allies himself with a strange priestess named Melisandre (Carice von Houten). Across the sea, Daenerys (Emilia Clarke), her three young dragons and khalasar trek through the Red Waste in search of allies or water. In the North, Bran (Isaac Hempstead-Wright) presides over Winterfell, while beyond the Wall, Jon Snow (Kit Harington) must find shelter.
