Past
Mystery, Inc. has been fighting crime and solving mysteries for a long time, and have come to appreciate one-another for each of their resourcefulness.

Erenaroonie’s Six Nights of Scares: The Shriekquel
As Erena is confronted by a mirrored vampire version of herself, the gang awaits outside the room ready to destroy the cursed mirror. Fred suggests the idea, before the group can hear someone scream, and it getting closer. Velma points out the scream, and Erena eventually bursts out the door, each of the members saying their catchphrases (expect for Fred, who says he still does not have one).

The gang, Erena, and the reflection go through a door monologue, going through all the doors quickly and in the course of two minutes. Erena eventually breaks and runs, and the gang follows.

In the credits, Erena tells the gang that she wishes she could be so living mysteries with the game, rather than the Halloween she has been made to suffer through. Shaggy also states that it’s odd Erena is having a much worse night than the actual group, which she replies. The reflection then tells Erena that she thought she loved scary things, which Erena quickly replies that this moment is an exception.
