I intimidated the tieflings. They agreed to leave. They didn't and just kept saying "what are you doing. Get out.". I freed Lae'zel. Damays and Nymessa attacked. I defeated them by knocking them out. Then Lae'zel said, "You like to raise that weapon to me? Let's see how good you are" or something similar. Then she attacked.

This happened in 4 player custom characters game with half Drow cleric, Drow fighter, Gith Ranger and human druid in wolf form. If that makes a difference.

Also, we came in from the direction of the crypt, so not on the path closest to the tieflings.
