As 発言しました によって other posters, unfortunately, there haven't been many, which is why I rely on my imagination and fanfiction writing. In my mind, there have been some rather steamy Quick moments. In reality, not many.
I can really only think of three, and they're short. One of them being in the pilot - it was deleted, stupid Ryan Murphy - where they talk and Puck acts like his usual sex obsessed self. It stars 13 秒 through the video:
link Then there's Grilled Cheezus, where Puck sang part of Only the Good Die Young to Quinn for a 秒 and she was all happy:
link She stares at him at 33 秒 and he sings to her at 47.
And then there was in the Brittany/Britney episode, when Rachel was 歌う the Only Exception, and they were staring at each other and she mouthed the words to him, which made my ハート, 心 flutter.
