Welp, we didnt see that coming!
Lets break it down.

The two take off for their family home, which Weller himself hasnt visited in decades.
What they find … it isnt good.
The entire room Reade and Zapata are led to smells of bleach, and they know something is sketchy.
The two then find a bullet shell wedged under a table, confirming said sketchiness.
Knowing they cant go to their internal FBI resources, the two decide to reach out to Patterson.
Joey tells her to go hide, giving her an address to head to.
He says that Oscar is unable to meet her there, as hes still cleaning up the Mayfair mess.
Jane heads back to request one last favor of Ana.
Jane takes off to catch Oscar making the pickup so she can follow him to Mayfairs body.
Sidenote: We need more Ana!
NEXT: Janes flashback tells us whos really behind all of this.
She starts to have flashbacks of the two of them pre-memory wipe.
Jane pushes the memory aside and approaches the cabin.
She wakes up tied to a chair, with Oscar prepping his next move.
These guys seriously have a messed up relationship.
They take a look at the painting and notice four stamps on the back.
Patterson puts in their birth dates and it opens the safe, revealing a single USB drive.
Im no super-spy, but thats a pretty basic code even with the little time she had to prepare.
Why notpull a President Skrooband make the code 1-2-3-4-5, Mayfair?
After doing her famous unscrambling, Patterson discovers through using the key david (ugh, the feels!)
that the passcode is IMSORRY.
The gang now knows the significance of the passcode and start to uncover Mayfairs dirty past.
Back at Wellers parents house, he and Sarah begin to dig under the fort in the backyard.
To their relief, they dont find anything.
With the tension lifted, they share a six pack of beer in their childhood kitchen.
When they run out, Weller heads to the garage to find more beer.
As soon as he walked into the garage it was obvious something bad was about to happen.
He drops the beer, runs inside, and tells Sarah hell be back in a bit.
Cut to the present, and we see Weller pull up to a site called, Fort Boone.
He starts digging, it begins pouring rain, and he comes across a yellow rainboot.
So, now we know: Jane is NOT Taylor Shaw.
NEXT: Back at the cabin of lies, more bombshells are revealed.
Jane starts to get flashbacks of herself extremely dehydrated and someone giving her water … Shepherd?
He claimed that Cade wanted to kill Jane as revenge.
The bombshell that really struck a cord, though, was Oscar telling Jane she is NOT Taylor Shaw.
Remember the born-in-Africa isotope thing?
Oscar tells Jane that Phase 2 is about taking down the entire government.
The two have an intense fight scene, with Oscar telling her that he doesnt want to hurt her.
Jane is relentless and wont stop trying to take him down so she can arrest him.
What did you do?
That is NOT the way we wanted to see Mayfair go!
The fun isnt over for Jane.
Now, he looks as mad as we have ever seen him on the show.
Jane sees the anger in him and is taken aback, already on the defense.
She says she can explain, but she can barely find the words that would help between her sobbing.
He continues to pain her by calling out her lies, her backstabbing, and breaking his heart.
He cuffs her, delivers her Miranda rights, and tells her shes under arrest.
What just happened?!

There was a lot revealed in the finale, lets talk theories!
