Either way, it'll be good. I mean, if he says it to Warrick and/or Grissom, it'll show the depth of his emotions, and Nick will be pleading with them to help get to her faster - not like they aren't already trying, but sort of in a "if we don't find her alive, then I'm dead too" kind of a thing.
But if he says it to himself, it's like he wants to be her hero and saves the day. perhaps the first time that he'll allow himself to verbalize how he feels about her (well, sort of verbalize, anyway!) LOL!
And yes - I'm way tired and have been online FAR too long! Thank god I have the next two days off!
