At Stacey's suggestion, I googled "Aubrey needs". Mine's a little screwy since Aubrey was a popular boy's name back in the day.
... at least a little practicality about her.
... an emergency dose of adrenaline on hand in case of anaphylactic shock
... a girl who likes music, romantic dinners, and is a big movie fan.
... this email to send another survey
... a ship surgeon for his new command
... to be the key central character at all times with the less attractive Maturin a close second.
That last one's my favorite.
