I don't know if anyone on these forums were around when the admins did that halloween play all those years ago, but i do believe they may do it again this year, heres the clues that lead me to believe this.

Exhibit 1:



As we can see, the ghost says 'Did i miss the show?' this is pretty obvious what it means, so i will go straight to exhibit 2.

Exhibit 2:



The sign next to the building says 'Murder mystery' and a few other words. If i am not mistaken, the play from a few years ago was also called murder mystery, however i could be wrong about this.

Exhibit 3:



If we look, there is a cave behind the building (Or so i think.) where the statue comes out. I may be wrong about this also, but the building could look similar to the one where the original play was hosted.

Overall, I think there may be a play this year, however, this building could also be an easter egg to the play. I am not too sure what year they did it, but it was many years ago for sure.
