Some good choices there, but you've missed out what was probably one of the best episodes of season three, and that was Lullaby That one would've gotten my vote, but instead i went for "Tomorrow"

Yeah! Where's Lullaby? Shouldn't that be on there instead of Quickening? 'Cause Lullaby was like the big ep, whereas nothing that significant happened in Quickening.
I chose Waiting in the Wings, but this is what I hate about s3! There are barely any stand out eps! I can barely remember what happens in half those episodes. Waiting in the Wings was definitely good though.

"Waiting in the Wings". The season three arc really doesn't work for me, but that was a great stand-alone episode. Classy, creepy ghost story mixed with tragic love triangle, what more could you ask for.
