I too noticed the "my" house comment by Lindsey. However, isn't this a home she moved into after her husband was jailed? I don't think he's even seen the place. I think for her, not having him there since the day she moved it would make her call it "my" house. He's obviously never seen it or been there.
Funny that I get a completely different feeling watching Lindsey and Tommy talk. I think they love each other. It was kind of sad to watch him hear his wife talk about the things his children are doing. Things he doesn't get to see and is missing as they grow. He laughs when he hears about his daughter coloring on the walls. And, he offers some fatherly advice of watching the children when they have the markers.
You can tell he's very lonely and wants her attention.
As for those eyes, yes they do twitch. But I think the strange look when he closes his eyes is caused by his eyes being so big, the eyelids don't completely cover his eyeballs when he tries to close them. It looks as if he has his eyes half closed.
But the rest of you can go on and try to diagnose something exotic that is wrong with him. Just call me when you've finally settled on what makes his eyes appear like that. LOL.
