One evening in Breaking Bad season 2, as Ted is about to leave from work, he stops by in front of Skyler's office to say goodbye. Ted appears to be attracted to her, just as one might say he did when he hired Skyler back in the first place, showing no intention of thinking about it twice. Marie reinforces this idea by referring to him as "grabby hands" in front of Skyler. But it seems widely accepted over the web that Skyler is not attracted to Ted.
But in this scene, Skyler appears to deliberately knock some stuff off from her desk and her expression of frustration seems totally fake. Ted of course immediately kneels down and picks it all up. That seems like affair-kindling to me.
Although we know that Skyler later on slept with Ted to get Walt to agree to the divorce, back then, Skyler was showing no sign of intention to divorce Walt, as is suggested by their discussion and peck on the lips just as she gets on her way to pick up Ted's birthday cake.
Their tone was pretty affectionate, and this was after the scene in the office.
So what else could explain her behaviour if she's not attracted to Ted?
