David blinked when she accepted his offer. To be honest, he believed she would actually decline it. Not every pirate captain was too keen on letting one of their keep spoils of victory for themselves. "I worked in the military. I wasn't 'trained' to backstab people." David spoke this, but briefly thought of how he was still quite capable of taking down most people in an honest fight. 'Honest' being without him using his powers to their fullest extent. "My name is David. Don't bother asking for a middle or last name." David then looked to her hand and decided to shake it. Mainly as a unwritten signing of their deal.
The captain (Which he mentally calls her from this point on) then invited him unto her ship. "Before I do, I would like to know the name or title of my new captain. Yelling the word captain when I need orders is bothersome." David still took a brief glance in her ships direction though. If only to make mental notes of what they may eventually need to improve upon. All he really noticed from this distance though was how plain it seemed to look. Just your average ship that can support a somewhat small, but full, crew. Its flag wasn't even that detailed, as it was merely a skull and crossbones motif...with some kind of stitched X over one of the skulls eyes.
This particular flag was of the most bother to David though. "...I never understood some pirates need to have that kind of flag up. It only attracts attention from the military, or worse, makes potential victims flee like bugs."
