No, it was unalloyed sequaciousness.
Query for the longtime players: Has Jack of All Trades been used before? If so, we can safely assume all remaining roles are ones that have been in play prior to now. It would be bootless for Jiro to give us 2 new roles when the first one to die would alert us to the possibility of a second. One, I could see, for mindsmurf reasons. Not two.
