No, you're not doing anything wrong. There is no 'right way' here. Simeon looks as though his intention is to lead you past the side passage, but that doesn't mean Kerlan can't investigate it. However, since Simeon is leading the procession, Kerlan won't get up to it, until Simeon has already passed it by. If Kerlan would like to ask why Simeon doesn't go investigate to the south, you're welcome to do so.

Simeon doesn't know what's down that way. It's just more UnderDark as far as he knows. The most direct route to the Vault of Larin Karr is straight on, however, but that may or may not be the best thing to do, depending upon what you guys wish to do next. Makes me no difference.[/sblock]
