Actually they would have had all of Derek's information from when the fire happened, when they interviewed him, they would have had to confirm it for case files. Plus they had him for a full 24 hours and in that time they would have figured out that the license was phony, especially if he used a different one for another job, but even if they hadn't and accepted it as fact it still would have been in their computer if not they'd get in trouble later in if he's involved with another case or they get an audit or review (does happen, sometimes they'll take police files for a personnel review or if they have a problem with case files or even if one deputy turns out to be dirty, they'll got through case files then)

I agree about the fire but the Darach timeline is still suspect and I don't think it was confirmed that it was 10 years ago, I know that the Sheriff asked Melissa for a file and he did say 10 years but it seemed like guesstimate, when I research for my job I usually start with 10 years when I search then broaden it when it doesn't yield results. If it based on Julia's medical file, most dates are m/d/y, especially on hospital charts, since one is missing it very suspect, unless it was confirmed to you. And Ian's Derek made it seem like Paige wasn't as long ago as 3 years.

So either Stiles' birthday was in April and canonically he'll be 18 right after Lyida or they messed up on the dialogue with Heather/he turned 17 during the Darach mess, not sure when Derek would have found that out, though.

I don't know if I made all of that make sense or not, sorry, typing this on my phone and I may have missed some words grammatically.
