7.5/10.
Four Sombra cultists plot to assassinate Twilight during a state visit, but one of them is a narc. A nice longform oneshot, particularly with the communist lore and tragic ending, it's let down a little by the central mystery of "who's the rat?" not being that riveting due to both an all OC cast (the Twilight tag is pure Feature Box bait) and its relative shortness meaning you can't care enough about them or their evil plan for the mystery to hold much weight. The ending is still very nice and melancholy.
