No true knight

They made the wall way too thin. Jon and Ygritte looked over the lip on the North side, turned around, walked across a little path, and were at the Southern edge. Aren't there supposed to be tunnels and passages through the ice? 700 hundred feet tall and 12 feet wide: you'd expect it to be swaying back and forth. The wildlings could have just dug right through it. The climb up the wall was thrilling though. As an action sequence, it was more successful than you normally see in a television show.

Ser Dontos still exists! He's a terrible juggler. Here's something subtle. Check out the scene where Joffrey tells Mandon Moore to represent the King on the battlefield. Moore nods, and they both glance at Tyrion. In the book, it's never made clear exactly who sent Ser Moore after Tyrion (Tyrion thinks it's Cersei). Just like the showwriters had Joffrey and not Cersei give the order to kill Robert's bastards, it looks like they also had Joffrey give the order to kill Tyrion! In fact, Joffrey only leaves the battle because he gets cold feet... it seems like Joffrey's original plan might have been to do in his uncle himself (with Moore providing backup support if things got hectic). And then have Sansa kiss the bloody sword.
