Hee hee - see I knew there were other "spying" scenes... I was just too lazy to go look them up. <g>
I'm sure I'm probably the minority on this one - but - stalkerClark doesn't bother me... and further more, he doesn't feel out of character for me either. Well, okay, a little out of character in the pilot - since he didn't know Lois that well yet.
But the rest of the times we've seen him do it - no. Clark was deeply and completely in love with Lois... and he was constantly looking out for her - whether that was physically or otherwise. So I could totally see him being possessive like this. I actually don't think of it as a "stalker" at all. Just a loving friend checking up on her... that's all.
I've actually used the "stalker" side of him (either actually watching her or just "thinking" about watching her) in several of my stories. Which we saw Clark *tempted* to watch her also, in the series (HIM for example).
I'm sure I'll catch a lot of flack for those comments, but, oh well. <g>
