"Old" Kiss - the kiss in front of the fireplace has always been one of my faves. Mainly because for me that was when I said "these two have 'it.'" Though really any of their "old" kisses make me happy. Even if it was just a quick kiss in the office.

"New" Kiss - I'll take the kiss before Nora's wedding to Clint (WTH was she thinking marrying Clint??) Again - it was the beginning of the new Bo and Nora. I rally liked the kisses at their wedding reception when they were all alone. Just dancing, eating and kissing.
