Loki personal life

Rating: 9/10 (24 October 2013)

I am curious what the IMDb community thinks about Loki, and his past/personal life. First of all, you have to love the name Loki, as in low-key; which he is kind of the antithesis of. Maybe he is not as outwardly animated as Jackman's character, but you can see tons of rage. Anyway back my my real point/question...
First of all, he never drinks. We never see him take a sip of alcohol. When the police chief offers him the whiskey at the end, he immediately dismisses it. Could this be nothing, sure. Could it be something, perhaps. Cops are notorious for being drinkers, as even a little reference from shutter island will support:
Teddy Daniels: Soda on ice please, thanks.
Dr. Jeremiah Naehring:Oh, you don't indulge in alcohol I'm surprised. Isn't it common for men in your profession to imbibe?
Also, the reason why this stands out to me so much is because there is also one scene where I believe Jackman's wife asks the detective if he has kids. He never answers the question. He defers to some generic line like "we will find your girl" but thats not before hesitating for a second. Maybe I'm thinking too much into this; but the hesitation and look on his face struck me. Is there a connection to his hesitation to this question about him having kids, his refusal to drink alcohol, and the reason why he solves child disappearances for a living? Who am I to say. But these are things that struck me and things I think about.
