Setzer watches the mimic go through the motions of copying their traveling companions' every move, at first slowly, then more and more quickly - they're obviously gifted, he can see that much, but he also knows that luck is something that no one can imitate. It just is, a force unto itself, and while maybe Gogo could learn to throw darts as well as Setzer could - that's something that can be copied - chance flows through dice and cards and cannot be forced into any set pattern.

He thinks that, right up until he watches Gogo cast dice with him - both of them balanced, both of them identical in weight and material and make - and stares in disbelief as both his pair and theirs show exactly the same numbers, every time.
