That would be an awesome promo pic! haha. yeah, I do see that something like that happening.
I've been thinking more about what may happen to Greg. And these are my thoughts:
Getting shot (actually being hit): This one is very tough because part of me is like, no they would't do that because its already happened quite a bit with many other CSI's. Not actually getting hit exactly, but there have really been only 3 very life-threatening things happen to CSI's. Holly, Nick, and Brass. And two of those were caused by gunshots. Especially sense the Brass almost dying thing was fairly recent. Not to mention how many times a CSI has been threatened with one. (Nick bunches of times.) So, for those reasons, no guns really.
But on the other hand.. we already know that Greg is very unstable with guns, or bullets rather (more so than some of the other CSI's) and we know he doesn't carry one. Also, the article said that he will be in the "line of fire". I don't know if that has to mean bullets/guns for sure, but your mind kind of jumps to that automatically. So.. this is possible, but I'm kind of leaning towards no on this one. I think they will be a bit more creative with this.
Getting beat up or thrown around: I've actually been considering this one a lot lately. Like, I can just see him processing an alley or somewhere dark when you see a figure come up behind him and beat him up some. Not real bad, but enough to leave him bloody and bruised. And then hes just lying there and the others find him. (Ugh, not a pretty image.) But something like that would be pretty good because its a pretty freaky thing and it could hurt him just enough for it to be considered physically and mentally painful, but doesn't have to be enough to keep him out of work for a long time. And they have a pretty wide range of how bad they could hurt him and where they could go with that. And that would leave him trying to decide wether or not to go back to the field, or the lab. Because at the lab, bad things do happen, but its usually because of an accident, not someone purposefully trying to harm him. And, I don't think that Greg has ever been put in a position like that that shows him exactly how mean people could really be and how fast he can be the body being investigated.... Of course, that part would fit in any situation in which he was hurt by someone on purpose.. but yeah.
The only problems with that would be the line of fire thing (we could find a way to work that in somehow im sure.) and the fact that unless they skipped pretty far in time, they might have to make sure some bruises and/or cuts were on Eric to make it believable...
So.. yeah.. just some thoughts.
Wow, I talk a lot. But I really have been thinking. Um... there are a lot of possibilities, but those are my top two at the moment, but are more than likely subject to change.
