I think they could've recorded the first of four Purple Parrots if David went first. He knew what he was doing, and althou his partner was probably reading Stephen King instead of the Temple map (I know someone made a similar comment about Jackie in the Oracle Bowl of Delphi, hope they won't mind I said this,) Eusinia was a fast runner. She probably could've made it out with the Cobra Staff if David went first (unless she tried scaling the central shaft on the way out.)
