Well, the rules don't say what it means to not be able to 'invoke their influence again'. A strict reading of the rules could be that it only applies to the Dark Bargain Move, especially since the Playbook Move Notes section mentions that it might possibly not be your Dark Patron that you call upon to sanctify these deals, leaving it open for you to have some other power (especially if you took it as an Advance Take a Move from another Playbook).
We decided that it also included your Demon Form because you failed to transform right after that failure, so testing that Let It Out Ability in the same way is not unprecedented? But that does feel a bit like it should fall under the same umbrella of 'not working'.
Drgwen says:
... I think. I also like the idea of foreshadowing the Invocation move, but that also feels a bit like a cheat. ...
I do see that point, but this too is not unprecedented. You were already —while 'powerless'— teleported out of restraints and brought home... as part of your End Move. This is actually why I thought of this solution, only afterwards did I look at the sheet and see the Moves and Abilities that could do that sort of thing.

... Wentworth. ... put her in his Debt ... So maybe HE comes in, ... and frees her? ...
Sounds great. We can do that.
Drgwen says:
... HE comes in, in demon form ... it lets Circe know that there is something to this demon talk ...
Yeah... and possibly sends
her into the looney bin in your place? Wouldn't we rather she have a sightly more gradual introduction, and do so when you are around to explain it to her?
I also don't see Wentworth barging in and showing his form to the hospital. That does not exactly fit the 'subtle manipulator vibe' of your organisation.
I can see Wentworth freeing you, possibly in a way that leaves Circe with questions. If you want him to show his form to her as your proof, that may need
another Debt? If you want him to bring her along for the ride when he spirits you away, that also sounds like an extra Debt?
We can work on the flavour if we agree to the premise.
