10. The Bear Pit, "The Bear And The Maiden Fair"
One of the best story arcs of the season is Jaime and Brienne's road trip. Although we see them briefly in the finale, Jaime and Brienne's Season 3 arc essentially comes to a close in this scene. When Roose Bolton sends Jaime back to King's Landing but orders Brienne to stay with his sadistic bannermen, it's clear that things won't end well for our favorite female knight. Jaime realizes this, makes his captors ride back to Harrenhal and does something genuinely heroic. He jumps into the pit where Brienne is being forced to fight a giant bear with a wooden sword, and he saves her life. Then she saves him. Romantic, right? The scene makes it clear that Jaime is somewhat of a changed man after his nightmarish journey with Brienne. We see that he genuinely cares about someone else other than his twin sister. As for the action sequence itself? Christie is riveting in this scene. The fact that a real bear is used (his name is Bart) makes it all the more impressive.
