Have you tried running to the correct pillar he wants you to go to, to see what happens?
I've found that when he falls behind and I reach the pillar, he automatically teleports near me so I can talk to me again.
So try that first.
Otherwise I don't really have much helpfull, other then maybe restarting the module (it's still early in that module), save/load and that sort of things.
he should join your party so make sure he does...if he dosnt then you mabye didnt say the right stuff? could always try attacking it and getting it to chase you to the pillar and then invising and leave for a bit till it becomes friendly again
