I'm going to be extra nit-picky and say that I think it would have been better had his hair been longer in the flashback. We know his hair was longer than in the flashback during some of his time studying physics because of the photo in "Hell Week", and the ex who became a nun said that his hair was shorter than when she had last seen him.
I'm not saying that it counts as an error. People can change their hair a lot over the course of a partly-finished physics degree.
Anyway, yes, the really obvious thing is how quick they were to organise the funeral. That's even worse than the "why is Mac handling evidence with no gloves and what about the chain of custody?" thing.
I liked the choice of flashback songs - one ridiculously upbeat and one melancholy.
Another nitpick. Whyyyyyyyyyyyyyyyyyyyyyy was she so eager to let go of her relationship with poor
? I get that it would be annoying to have someone sign you up for a job abroad without even telling you, but (a) she liked the thought of travelling and (b) the least she could have said was that she didn't want to go, but perhaps he could go for 3 months and then come back to her.
I would have waited 3 months for him.
