Ramblings: Are TPTB trying to tell us something?? (Lost)

So, I didn't get a chance to watch the Lost season finale on the night it aired, but I watched it the next day online. I was admittedly sitting pretty close to my computer screen, which I'm now grateful for, because there was a tiny little thing that happened to catch my eye, and I'm sure I wouldn't have noticed it at all if I were watching on TV.

Still, I couldn't be sure whether I actually saw what I thought I did, or whether my femslashy brain was just imagining things. But thanks to screencaps, I was able to check, and sure enough.....
