Less thankful than he should be for Howard's patience with him time and time again, the Doctor is so focused on the door that he overlooks his charm. As the entrance creaks open, Sigma feels as though a heavy yoke has been lifted from his shoulders, and even the intense pain in his leg and chest no longer seems so sharp. "K, I am glad to see you," he sighs. Pinning the cat down gently with one arm, he gestures for him to come inside. His relief draining him, he is not sure he can stand up again to meet him.

"Howard, this is K. We met outside of the Arena. Believe me when I say you can trust him," he reassures, though each statement he'd made had been a lie. He knew Howard to be incredibly sharp for a boy his age, and he hoped the sincerity in his voice was enough to lead him off track: to convince him that this was not the one Sigma wished to win.

Otherwise, they'd have no alliance at all.
