It was beautiful episode. The way they opened Abby's char for us more and the way her day was so awful. That little boy looking for mom, the woman talking about getting a child and once having one already.. and her ex.. it was all too much, I agree and the way she ended up to the final scenes - getting bear. It won't lead nowhere good.
But the real pearl of this episode was Carter and his storyline. The way he met that stabber again. Superbly played. It was so real that it was frightening. And that song on the background when he rushes to bathroom and later at home takes it up with her mother who has not been there for him. Brilliant acting. Really!
