Debiassi, reading the posts from TP, it does seem that RW claimed both to the subcontracting company and the insurance company that he would be P1. He may be a Walter Mitty, he probably deep down knows that he couldn't handle the task and found himself a "passenger" on each and every trip that he could use in case an IFR plan was required. It would not surprise me if the flightplan filed on this particular trip, if indeed IFR, was in the name of the "passenger".
He did the same on the last trip covered in the other thread, finding an unsuspecting pilot to accompany him, in that case a newly qualified Italian girl.
TP, as you stated that the insurance company has settled, maybe nudging them towards RW for recovery of their losses due to fraud/misrepresentation could be something you may want to ponder.
