Another thing we can do to help Etienne find a place on the crew is look at what ship duties he could fill that others haven't filled already. You can refer to the OP or the Spell & Crossbones Group for info on various ship duties.
So far we have..
Katerina - captain
Barrington - master gunner / quartermaster
Nia - sailing master
Old Zef - boatswain / carpenter/ artillerist
Caillou - lookout / navigator
Kid - crew (rigger)
I actually think that making Etienne quartermaster could work well, if [MENTION=23484]Kobold Stew[/MENTION] is ok with that? Handling crew disputes with rousing wrestling matches, and exercising his mercantile skills towards outfitting the ship, keeping inventory of supplies and treasure, and such.
Alternately, if he has healing ability (and you're willing to buy him proficiency in surgeon's tools) he could make a fun sort of Surgeon? Inspiring the crew, telling tales of various ventures to keep their mind off the pain, prescribing "magical remedies" that rely on simply herbs and a good bit of psychosomatics.
Alternately, he could be made First Mate? This would make him more of an apprentice to Old Zef and Nia Steeleyes, and might be appropriate if he has less watercraft knowledge than others, so it would be more of an "in training" position. This might double up nicely with him being a raconteur, since the First Mate is often sent to handle mundane matters ashore involving maintenance of the ship that require him to interact with lots of NPCs. Sure, a lot of people could be hired on as First Mate, so why not hire someone entertaining? And with some mercantile contact that could come in handy?
Anyhow, just my five pennies.
