I am going to keep this fairly general in nature, so as not to have to rely on Spoiler tags.
We were playing a scenario which resulted in a Mythos Event having us place a monster on the board in room X. In the text of this placement (what I would call flavor), it said that the monster moved into room Y, scaring a character that was already in room Y, and thus resulting in the character fleeing into room Z.
It then actually gives you a specific order to move the character into room Z, and afterwords shows the character in room Z. It never specifically tells you to move the monster into room Y, nor does it ever show the monster in room Y.
So, are you suppose to leave the monster in the original room X (where it was originally placed), or are you suppose to follow the "flavor" and move it into room Y, so it actually "scares" the character in room Y, causing it to flee to room Z.
I hope the above makes sense.
