Back in King's Landing, Joffrey receives the new about Robb and Catelyn deaths. As we could expect, he intends to serve Robb's head at his wedding right in front of Sansa. I just can't wait to see how Joffrey dies slowly. Please, writers, make it a really really slow death, is the least we deserve. However, Cersei and Tyrion try to calm the king down as they will not tolerate this kind of behavior.
After winning her last battle, Daenerys waits for the Yunkai's slaves to meet her. She's in some way suspicious about their behavior as she thinks this slaves might like their chains. However, slaves go outside Yunkai to meet her and recognize her the new masters by saying the word "Mhysa".
Interesting facts: did you know that "Mhysa" means "mother" in the language of the Bay Low slaves? Also, let me remind you that this is not the first time Joffrey wants to show Sansa some relatives head. Do you happen to remember Stark's head on a pike?
