My bet is on a classic misscummunication. Maggie should have written "ESCORT" instead of "PROTECT" in the g-string message.
We know from the book version of Book 1 that Maggie and the Great Minds do not see precisely eye-to-eye on Parson.
There is a scene towards the end where we see the Great Minds wanting to take Parson captive and interrogate him. Maggie warns them that this would cause a civil war in the Magic Kingdom, but the Great Minds seem to think it is important enough to be worth it anyway.
Maggie, on the other hand, wants to give Parson free reign to think and act how he does, and convinces the Great Minds that their goals (which include dealing with "the Charlie problem") are better served by them leaving Parson be.
I think Maggie probably just wanted the Great Minds to escort Parson, but they themselves are uncomfortable with letting him go again and so are taking him captive.
So I'm guessing on disagreement more than miscommunication. But we'll see!
