Jimmy will not second guess Clark
- He's very Genre Savvy, he's known Clark for years, he's seen enough scifi to have guessed that the League of Lois' was on about evil alternates, he's seen enough scifi to know evil alternates existing doesn't mean your universe has one, the Vale incident likely ingrained some skepticism towards possible slandering of his buddy, if he actually asks Lois where this is from he'll get the answer 'the "chaos god"'.
