S4·E92 Moth at the Hoarse Tractor Driver's

There was a film called "Dead Mountaineer's Hotel", in case anyone missed the reference. This episode has a nightmarish ending. It's the only episode with a bad ending. Masyanya dies. Even if in the form of a moth — still... The episode was planned to be the last Ragtime. And the last Masyanya episode altogether. Which is why she dies.
