While I enjoyed the episode, through the whole the trial by combat, the way Oberyn kept repeating himself made me think "Hello, my name is Inigo Montoya. You killed my father. Prepare to die." I really liked his character in the book and the actor did an amazing job of portraying him, but I knew his fate so I didn't get too attached.
Honestly for me, this last episode actually finally made me like Sansa. Through 5 books, she manages to stay a fairly weak, naive sap that probably wouldn't have survived if not for others protecting her (my opinion). But the show version having her finally develop some cunning and survival instincts? Bravo. She might finally be interesting.
And doubt she actually has a thing for Baelish, but wised up to the fact that she can use him (for protection, to gain power, etc) instead of it being the other way around.
