Irish must be telling the truth if there is one Scum role in game. He even used his starting item to make full use of his ability. Jeod's primary attribute was the three items he had, each one when activated would should allow him to counter an ability, since each one has to give him a limited passive.
It's a matter of timing as you know, the earlier a vote on Jeod shows up the harder it is to justify them being his partner, since those votes are more likely to result in getting him lynched than later bandwagon votes.
