Lex narrowed his eyes, studying not the chameleon, but the soul signature that seemed to be overriding the chameleon's consciousness.
To be honest, the challenge seemed entirely inconsequential, and in fact even seemed detrimental to him. If he won, he could understand the motives of the chameleon, but if he lost, the Inn would owe a favor. The limitations or restrictions of the favor were not mentioned, which made it very open ended. Furthermore, Lex strongly suspected that KD, the person behind the scenes, had a system that would enforce the conditions of the bet. If the conditions weren't met, the system would likely ensure heavy consequences making it so that no one ever reneged on a bet, regardless of how steep the conditions were.
"To be entirely honest, my inclination to accept this unnecessary bet of yours is not very high. I don't seem to have any actual reason to accept your challenge, and the benefits you're offering aren't remotely equal to the demands you're making."
