A Bird in the Hand, Two in the Cage

To try to even the playing cards, RED hires a tenth mercenary. Though the new class is a girl, she's capable of whatever task they put her up to. In response, BLU starts using loopholes in the contract to defy everything that's been done before and put the very lives of the REDs in danger, regardless of Respawn. Can Sparky's "friend" save them until a compromise is made?
