Bhaal wont follow me into candlekeep and to imoen?

can anyone help me here?

Keep Bhaal close, he'll enter the door after you. And remember to talk to Imoen first. You might try wounding him first. If none of these work, try the patch.

He is not coming through the door still....

Hmm, you could test if it's a bug by reloading or starting a previous game. Then go in a building where you know you will be attacked (the four guys inside a building in the bridge section are excellent) and when any of them starts hitting you in close combat, go out. If they follow, I've no idea why Bhaal doesn't. If they don't, it's a bug in the AI or something similar. Got the patch already?
