Hi Koki, nice to see a new poster who also makes sense!
I have also put forth this same "theory" in the past.
It may or may not turn out to be true, but if it does, it would NOT surprize me in the least (that Marty was "working with DM" the entire time). Knowing the incredibly
manipulative nature of the Church of Scientology, where "reality" is simply something to be "manufactured", I put NOTHING past them in terms of
intentional deceit and
contriving appearances to "create an effect".
The Church of Scientology has a history of
staging events as a way to control perceptions. This is easy for them, because "truth" is meaningless within Hubbard's framework, and the ONLY thing that matters is what any person can be tricked into "agreeing with". To them, REALITY = AGREEMENT, and "truth" is largely irrelevant. It is typical manipulation using ARC. Create some "understanding", such as "Marty has left the Church, hates DM, and is forwarding the true wonderful goals of Scientology", and thus tap into the basic "help" motives that originally attracted many to the cult. And, pull together all the still-existing fanatics who could be brought back into the Church eventually by some
magical merging of Marty with Miscavige at some pre-planned moment in the future.
Just as they
staged events to try to frame Paulette Cooper in a crime she didn't commit, so too could this entire Marty Show involve another grand "staging of events" - for the exact purpose you described (to unite them together stronger than ever at some time in the future).
While I don't "believe" this scenario, lacking sufficient "data", I would NOT put it past these lying scumbags.
