Yeah...I already knew that. But, the reason Deepak was even there at all, I think, was because he knew Natalee's family was there and they were looking for Joran. Joran said himself that it was unusual for them to hang out together two nights in a row.
yes, thats the whole point......paulus said "stay there, we're coming to pick you up".....right then deepak and joran knew they had a serious prob and split to scheme.....and paulus and the entourage wasted time driving to and from the casino and looking for joran at the casino.......so deepak and joran had maybe as much as 20-30 minutes alone together from the time they knew the baloon went up until the entourage got back to paulus house to confront joran and (unexpectedly) deepak. Unfortunate for paulus, joran, and deepak, their first words and everything they said was at that time in front of witnesses and paulus had no chance to coach them until afterward.......
