Paula represents Traceless's cat as well as Traceless himself. This is on paper a potential conflict of interest, since the two of them live together and spend time together while Traceless is backlashed, just like many esper partners do - but there are no agents Cricket is reliably willing to talk to directly, he needs a fair amount of disability accommodation for being a cat and can't tolerate anyone but Traceless well enough to get it from anyone but him, and in general he's just a huge pill and operates in the world with Traceless as a buffer, so Paula does the job whenever Cricket is between trial-period agents who seem for a week or two like they might work out.
