I see Flack as older too, mostly because of his position. Which I think it's safe to say he's had for quite some time, since he has his own "boys" among the police officers, and usually seems to be in charge of most of the SWAT operations. Also because the other homicide detectives in the rest of the CSI franchise (except for Angell, who I'll get back to) seem to be in their early 40s at least. Not that I think Flack's anywhere close to 40 :lol:, but I can't see him really commanding the respect of the men he does if he was half their age. At the very least, I think he might be the same age as Danny.
Angell, the only concrete age I'm sure of (said Dunbrook's newspaper in "Pay Up"), was 28 and still a homicide detective. But then, it was implied in "People With Money" that she had just finished being a trainee, so I don't think she was at Flack's level yet.
I'm finding it a little hard to believe Lindsay was supposed to be 24 in Season 3. That'd make her 23 in Season 2. And every biography I've ever seen on Lindsay says that she worked for three years as a CSI in Bozeman before moving to New York. Which would make her 19/20 when she started out as a CSI, which therefore means she was working on her forensic science degree before she'd've even gotten halfway through high school...yeah it goes on. Are we sure the diner incident happened when she was fourteen? (I've been under the impression recently that she was at least sixteen, maybe seventeen.) I've learned that TPTB mess with the timelines like whoa, but this seems huge even for them.
Hawkes' and Adam's ages seem to make sense, for the most part; I've aired my thoughts about Stella being 34 before, but Mac being 45...it may be a little off, but that doesn't seem like too huge a leap. Unless there's a reason 45 doesn't make much sense?
