Everything about this episode is good and believable except for Sophie. We are watching 2 episodes a night, so all the preceding episodes are still fairly fresh in our minds. And what we've noticed is that up to this episode, the interaction we are shown between Nate and Sophie is light, flirtatious banter. There's no real emotional weight in their discussions; even the argument about when they first met (shown in "The Mile High Job") was fairly teasing. And then suddenly in this episode Sophie has become a very pushy, demanding woman. Her character seems to have jumped overnight into a possessive, domineering *partner* with a higher stake in the relationship than we've seen so far. Instantly. Granted the topic is Nate's drinking, but she comes the heavy on him in a very unpleasant way. I don't agree with his drinking but I certainly understand why this interaction irritated him so much. Bellman acts it well, but all of us watching feel that they moved too fast with the Nate/Sophie relationship this way. This is the behavior of a woman who's got a far more serious investment in a relationship than we have seen between her and Nate so far.
