"No, we didn't too far on this level.  We came through this door <points to the west door that's further south of you> - we didn't go through that wizard's bedroom.  Then we checked out this door and found ourselves fighting those two bushes as soon as we came through the door.  After my fellows died, I was trying to make it back out before I got attacked abd where you found me."
So you guys exit, go the 20' south to the west door, turn east for 20', and are about to turn a corner south when a group of filthy, beast-like humans run into you.  They stop short and mill around, seemingly surprised.
(Yea!  I have upload capability!  You have to put the second map below the first for it to make sense.  B's are the Bushes, R is the Roses.  In the big room and the garden, I only showed what you could see from where you traveled or were).
