That's not what I would call a fake outing though. Are we talking about the same thing here? I thought a fake outing would either be done a) by someone to save oneself, or b) by the JL to get the sorcerer & Co to reveal themselves or c) by someone trying to fool some middle man into doing the outing and then eat the same middle man to cover up his step. If it was something like c) and it happened on the day Avernite was first run up it might point to the Purples so would be really interesting to know who know what and why the fake outing didn't happen.Really doubt that Jeray was in on it. Alxeu didn't really tell me to not have Jeray hung when I mentioned I didn't want jeray and LK hung (which was due to that spy report I got on MC's death).
He seemed to be indifferent to jeray dying or not, though he could have feigned things. But he did outright tell me in PM not to have de Chat hung, so him bing indifferent to jeray does suggest he wasn't affiliated with the JL.
