[Scott is the picture of what he looked like the day he had called Lydia to show her the tape Stiles had left him. Broken and hurt, and a little bit like a kicked puppy. He looks every bit the way he feels--like he could fall apart at any moment. And he kind of wants to...and Lydia's the only one he could turn to when he feels this way anymore.
He doesn't speak for awhile, he just moves to sink down into a heap in a chair. Mostly, he doesn't know what to say, because there isn't much that she doesn't probably already know. He so just doesn't want to speak, for fear of actually losing grip and breaking down, which he hasn't actually allowed himself to do yet. He had to do this, be here, for her first.
Finally, when he does speak, it's soft and carefully because he doesn't want the emotions he's feeling to pour out yet.] I was wrong... about Thomas.
