In Season 3 Episode 05 - Mas, there is a scene in Ted's house, in the bathroom, where Skyler puts down a towel under her feet. In earlier episode Ted speaks about how the contractor talked him into having a system that heats the floor.
As I see it there are 2 possible explanations to Skyler's action: one, that the floor had become too hot/cold for her liking or two, her current stance in which she starts to doubt her relationship with Ted and softens on what Walt has done, makes her feel guilty. So it could be her way to put a sheet(read towel) between her two lives.
Which is it? Is there something I missed or am I reading too much into a simple scene?(I sincerely doubt that. Nothing, absolutely nothing is inconsequential in Breaking Bad).
PS: I remember moment before this particular scene Ted walking out of the shower and hugging Skyler from behind and asking her to keep back some of her things since she comes in regularly. He did not mention the floor being too hot/cold, so the first possibility looks dim!
Please mention spoiler alert in-case you reference something that happens after this episode.
