This is where I really begin to feel disadvantaged by the fact my local tv network screws us over in terms of airing CSI - we're only up to "Lovo Motives" and thus I haven't seen "Leapin' Lizards" or "Big Shots". I've seen a clip from the former, but there is nothing for the latter. And I think it was fear of his mothers reaction that made Greg cry. I have a feeling he's actually half scared of her - of her herself, or hurting her. I think it would probably take Nick a while to convince Greg to open up. I think Greg would be at a point where it would be hard for him to show any emotion without a lot of convincing. Nick would definitely have to win Greg's full trust, which probably wouldn't take much. But Greg himself would have to learn to let go, and that is a bit harder.
