David can and only says "Aw, seriously?" Due to a lack of things that he can say, David's personality is somewhat of a mystery. However, him saying "Aw, seriously?" shows us that he can be quite whiny and a person who complains a lot. David is also quite antisocial, often refusing to follow the directions of others and quick to shout his catchphrase whenever greeted with conflict. Though at times he is helpful to his team, he still has bouts of unruliness and stubbornness.
