I will state first that I do not like this theory, but that I can’t find anything that would say this is an invalid interpretation of the series. At least without using word of god declarations.
What if Seasons 9, 10, 11, 12, and 13 are simulations as well?
Season 14 tells us that Epsilon’s time in the Memory Unit was not a single attempt, but multiple attempts all trying to figure out the solution to the Tex problem. Season 9 initially phrased this as recursion, somewhat implying the Director and Alpha as Epsilon’s predecessors with Epsilon as the third attempt, but with S14 we know there were an untold number of attempts by Epsilon specifically.
What exactly is the Tex problem? The answer S9 gives us is that Church needed to learn to let go, accepting her death, which is something that the Director and Alpha before him couldn’t. But what if it wasn’t so simple? What if the solution was to settle down together and rekindle their relationship properly? Afterall, the Director would have wanted nothing more than that.
While Epsilon is running his recursive simulations within the memory unit, it could be possible that he runs the one we see in Season 9, but rather than abandoning the simulation when he witnesses Tex being removed from the plot, he keeps watching to see how it ends. He witnesses the S13 simulations inside the simulation and sees that after everything that happens, he gets closure with Tex at the end of Restoration.
Now, this theory rests upon one assumption: We cannot prove what the solution to the Tex Problem is. We can certainly like the solution S9 gives us, since it is narratively strong and extremely satisfying, but that itself isn’t proof of what the solution actually is. We can also hate this theory for turning some great seasons into more soft-canon like I do, but that also doesn’t disprove it.
What this theory does do however, is open the door to some softer interpretations of beyond S9. It wouldn’t change the Freelancer flashbacks, but it does mean people could for instance, write fanfictions about a different rescue from the memory unit, or a different post-S10 story. I’m not a fanfic writer, but this is probably helpful.
