I loved the Jack/Renee heart-to-heart, and during it I was thinking, "Kiss! We're running out of time!" But in retrospect, I'm glad they didn't. It was such an amazing, emotional moment, that it didn't need to be romantic.
I thought the finale was just made of awesome. Tony broke my heart, but Kim redeemed herself, Renee was thoroughly badass, and JACK. Kiefer's acting is beyond great.
Can't wait for next season.
Like, actually, I can't wait.
