Thunderbolts Theory

So I have a theory about how things might pan out at the start of Thunderbolts. This isn't a spoiler because I am only guessing I am not an insider (just a regular person).

Here's what I think might be going down.

- Sentry has been created throuogh a series of experiments, probably supervised by Val and most likely secret.

She then starts using Sentry to conduct a series of false flag attacks because she wants to reinstate the Avengers and that needs an Avengers-level threat

- Val wants the new Avengers to be under government control (really her control) and this brings her into conflict with Bucky who wants them to be semi-autonomous and under Sam's leadership. This could be the basis for the Congressional hearing we see in the trailer.

Val is planning to reveal Sentry, her "solution" to all the attacks but he has been opposing her for some time.

- However something goes wrong and Bucky is getting increasingly suspicious hence his remark in the trailer about there being something out there and assembling the Thunderbolts.

He finds some information about the experiments and goes to confront Val with his new team. This is the point where she reveals Sentry who probably gives them all a good beating.

- At some point something causes Sentry to be taken over by The Void and Val of course loses control of him. He goes on the rampage in New York, killing and causing chaos

- Val in desperation (assuming she's still even alive) now turns to the Thunderbolts in desperation and begs them to stop The Void.

I know of course that none of them could do that so The Void can probably only be stopped by appealing to Bob's good side like with Hulk but what do you all think?

I'm probably badly wrong but hey this is just for fun.
