Given Bob lived in a one gas station town and everyone seems to know everyone, if he had cheated before then I suspect his wife wouldn't have been surprised by his infidelity. So, I'm inclined to think it was really a one time and will-never-happen-again thing, but, I agree, the plot point was poorly written. As was the progression of his disease. Can Kawasaki Syndrome trigger symptoms *that* fast? And cause an aneurysm to go into overdrive like that? I seriously wonder if they ever consult an actual doctor!
House was awesome in it's early seasons and one of my favorite shows on air. I would spend hours analyzing it. Now? Not so much. ;) But it still has it's moments. I especially liked the Chase stuff last night. And the show is definitely viewable, unlike GW or Ultimate Force. ::shudders::
