When this started with the saccharin sweet family of the EMH's I really wasn't looking forward to the next 45 minutes. I thought it was going to be cringe-worthy display with the crew trying to get him to understand that it wasn't what a real family was. While this is essentially what happened. Having B'elanna do it the way she did worked fantastically, and became quite a touching episode. I love the Doctor's attempt to just outright ignore it, only for him to go back in after Tom's rather well delivered speech. That final look of Picardo's was great. Totally devastated, yet at the same time trying to get his head around the whole thing.
Oh yes Tom, the B story. Nice little plot. Nice Trek without really doing much. Shame it was so far removed from the Doctor's story, which seems to be the case, just like with The Swarm. As for him and B'elanna. Those two really need to admit something's going on soon.
