I was watching a rerun of this last night, and I seem to have missed something.
At the end, Lady Mary tries to burn down the house. Remmie wakes up to find the place in flames. He raises the alarm, everyone goes running outside, and Remmie goes into labor. The Professor is drafted to perform a C-section. (We're not even going to discuss that idiocy.)
Now, I know that the other Remmie said he was going to fight the fire. But... When Quinn and Wade finally catch up, Remmie and the Prof are in a nice room - totally untouched by fire! I thought this blaze was supposed to totally burn down the house, leaving nothing to chance. What gives?

Another nit: At the end, Quinn points the controller UP to activate it. Yet, when they show the hole, it's right above floor level, not above head level, which is where the controller was pointed.

One nice nod to Dr. McCoy: Professor Arturo protesting, I'm a theoretical mathematician, not a butcher!
Dr. McCoy, we miss you.
