Duet? Be interested to hear why it’s in your list of comfort episodes. It’s a stunning hour of television, but it’s one of the most uncomfortable episodes for me to watch.
Hmmm, I might have misread or read into the OP too much, but I love suspense/mystery/twist episodes and this one really delivers, keeping me hooked in its universe. True, it tackles very heavy material and has a downer ending, but it's one that also feels like it may have been made with Ro in mind.
