It's because she is caring his child.
Same thing happened after Woodrough was shot, they cut the scene to his wife watching tv and she started crying iirc.
I laughed when it happened with Woodrough, I can't believe they did the "psychic baby-daddy death crying" scene twice in a row.
My biggest problem with the finale was there was no reason for it to be 90 minutes. It really did not feel as if they packed 90 minutes worth of plot into that ep. It felt like they stretched out a 60 minute episode.
It was so slow at times. Scenes of people staring silently or musical montages on top of nothing. Long shots of people walking and standing. Conversations that went on forever for no reason.
The biggest surprise for me was how unconcerned any of the characters were with clearing their names. They couldn't wait to run off to South America. And THEN Rachel McAdams suddenly becomes very concerned with laying down all the evidence and divulging the truth?
And why'd she run off with Vince Vaugn's wife? They don't know each other AT ALL.
Hey, you think they'll meet up with Dexter's kid and that serial killer lady?
And what's the timeline here? How did Rachel McAdams fall in love with Colin Ferrell after knowing him over two brief investigation periods? She's been super cold and uncommittal towards men all her life and she falls in L-O-V-E like a school girl with Colin Ferrell after about a minute.
And before all those "you watched it therefore you liked it" comments come in, you have to fight the "you can't judge it until you've seen all of it" people. This was a mediocre summer show that took up an hour a week, there's no hockey. There's nothing else on on Sundays, it's not that big a deal to watch a middling show.
