he should be at the far SE end of the docks by the boat (on your map there are 2 boats, its the one on the right you need to be at)
if he is not there and you followed all the proper steps (check the walk through for Brynnlaw), then it looks like your going to have to do it over again
p.s. #8 is missing on the map in the walk through, but its where i said it would be (i have reported it)
