Ray and Ani find out the underwhelming truth that Caspere's killer is Leonard, the set photographer they briefly spoke to on the set of that Mad Max-esque movie. Len and his sister Laura intended to kidnap and drug Caspere to get information about their pasts (Caspere had a relationship with their mother), but during the interrogation, Len went a little too far (an understatement) and killed him. It was a weird and unexpected reveal, namely that such a minor and relatively dull character turned out to be the killer. It's probably better than a ridiculous shock reveal of a prominent character being the killer, but even so, it wasn't exactly a thrilling revelation. When Ray caught up to Len about to kill Holloway and Len said, "I am the blade and the bullet", though? Comedy gold.
