This is entirely tangential, but I was proven correct when it comes to StM being two episodes shot/aired as one. Not only did it feature two separate "title card" sequences and have two different directors attached to it, ABC Com recaps it in two separate recaps.

Congratulations. Your two cookies baked into one with two different kinds of chips made by two different bakers is on the way...
Meanwhile, how did you actually like the episode(s)?
