The clone shrugged. He didn't feel like arguing about being a copy - he was smart enough to realize that the odds were in favor of him not being a real Time Lord after all. Though he smirked when the Doctor didn't seem prone to give up his futile hopes.
At the mention of Shannon he shook his head. "I simply put the facts in front of her," he said. "It's much better than what you're doing, giving everyone false hopes. If you like staying in charge so much, try to avoid making promises you can't keep." He shrugged his shoulders. "Sooner or later they'll realize you can't get them out of here. Someone already has."
"This city is too small for both of us?" he replied, mocking the Doctor's tone. It came only too easy to a clone. "Meet me in front of the saloon at dawn!" He laughed loudly. It was funny to see how the Doctor, for all his claims to be a rational person, was upset by him. "Don't worry," he replied bitterly. "You see, I don't have a life to live. I'm just a puppet in the hands of whoever designed this game, just like you are. The difference," he concluded, glancing towards the museum, "is that you and the others still have some time."
