So far I think my char would had got escort booked to him (without his knowlegde) as sort secret method get him some relief by the company council (as he is workholic). So imagine Vanessa would had been one hired for that purpose (and told keep her exact escort nature as secret so Adrian would not be upset but point being quietly seduce him into a carnal cruise). So Vanessa could act her role be just a assistant/as someone hired to show around the ship what it has to offer.
