I call BS. You start off saying the entire thing is an homage to the rom com/ heist trope, but you're only issue with the episode is that it used a shock based trope where the bad guy unexpectedly shows up at the end.

This is exactly what they went for and executed it perfectly. Literally zero notes.

Nowhere here did you mention this being the ONLY episode that leaves her "superpower" behind. TRUTH laid bare throughout the entire episode, but you're upset at the "unbelievability?" Take a walk.
