Okay, I'm still catching up (slowly) on all I've missed in the last two months when I've done almost no reading.
This was wonderful and made me glad I went back to check what I missed. Everytime I saw this episode, the fact that Clark fell asleep bugged me. I can hear my husband's voice in my head, who complained loudly, when a woman you've been in love with for over a year starts to express their feelings for you, you don't fall asleep.
This explanation was very believable and in character for Clark.
