His power play and what seems at this time his best pro-town ability.
I think an ability thief/copy could be equally as scummy but Orange here is pushing the suspicion on Jeod.
Orange was very quick to put out the theory that the gun only kills scum. When Peanuts died from Jeod's action no alignment was revealed. We know this also from the opening rules. Despite that, he was certainly hoping that Jeod's character would die and solidify his argument against him.
If Oranges wants to hold to this theory, then one could say that he and Jeod are not scum. On the other hand, without Sunflower revealing any hidden details about her gun that would otherwise help us resolve this case before day's end we're left seeing these two continue to squabble.
