I took this as one of the (first?) instances of TM's friends being able to sense when he is in danger. Of course the most obvious example is 4.1 Home from the Sea. It's not that he changes his mind, he just senses that TM is in real danger. Also, although we all know the guys would all lay down their lives for each other, they rarely (if ever?) speak of it, so I found T.C.'s line when they spot Thomas on the roof interesting: “There’s my Thomas! Here we come, baby!” It just seemed a tad outside the "macho line" they usually adhere to.T.C. changing his mind about not helping Magnum and arriving *dead on time* with Rick;
Elisha Cook's makeup (and his role) is so bad it almost kills the whole episode. The only reason I bumped it up to 7.5 was Patch Mackenzie and the fact that in at least two of her outfits, she seems to have taken the Charlies Angels approach to foundational garments.
As far as what T.C. was delivering, even though the container was totally wrong for it, I always assumed we were supposed to believe it was whatever cryogenic agent the bad guys were using to keep Farber frozen. Which would explain the heavy gloves they used to carry the case also.
Last but not least, for the sniper to have drawn a bead on Thomas lying on the couch like he did, he would have to have been aiming through the window on the stairwell landing. For that to work, the shooter would have to have been about 30 feet in the air over the property next door (assuming the actual estate layout) or over the tidal pool (assuming the guest houses fictional location behind the main house portico).
