Dash is a particular a friend of Copper, and the two are almost always seen together. When Able was left wounded outside the garage, they found him and brought him inside. Dash is bold, argumentative, and willing to cut corners for his own benefit. He talked Mara into giving himself and Copper time off from work, and later undercut her authority in front of the other mechanics, stridently convincing them to ignore her instructions in favor of his own. However, he did demonstrate concern for the safety of his fellows, and followed Mara's lead willingly enough when shown that her method would work.
