Again per above post, JE hired AD to investigate the claims of 2 victims during the pre-trial. Undoubtedly JE offered the use of his plane. In corporate world be perfectly normal.
Yes, could have been trial “evidence gathering” trip (Montreal is human slavery center, maybe?) and Dersh’s contacts were known bad people.
If the threat was to expose that trip as “something other than business”, Dersh would be “cuck’d”.
