I believe the incident that sparked the discussion was our first play of Base Raiders (aka the birth of Professor White.) Caleb was handed a pregen character who was a recovering addict, and when he found the super-powered drug supply he claimed them all. This super-powered addict became the super-powered dealer we all know and love.
Caleb's argument for the action was well-stated, but I feel he left a bit out of it. He was wearing three hats at the time- character, player, and playtester/fellow designer. His actions were not only in character, they were also an example of what a character could and would do; wearing that third hat, he helped to show a potential rough spot in the scenario. Overall, 2 out of three hats supported his action.
