Humanitys survival was never certain, warns Setrakian in a chilling voiceover to begin The Fall.
He recalls past incidents that almost ended the world, such as the bubonic plague and Spanish flu.
One final spin of the wheel, says Palmer.

This is the end game for both of us, one way or the other.
A weak old man is stumbling down the abandoned streets of New York City, barely able to stand.
A close-up reveals its Eichhorst, who clearly isnt responding well to all those silver bullets he took.

Luckily for Eichhorst, he still has some friends.
A pair of strigoi soldiers kill the humans and carry their injured brother to safety.
Unfortunately, some uninvited guests crash the party.
The two strigoi soldiers from earlier return and gun down Palmers entire security team (R.I.P.
Duncan, we hardly knew ye).
One of the strigoi isnt just anybody its actually The Master in his latest form.
They both fall to the ground and Palmer soon rises with red in his eyes.
Its clear: The Master has found his new body.
Now for the moment no one has been waiting for the return of Zach.
Hes just being a normal kid and playing in the dangerous streets with his pet feeler.
A concerned man sees the boy alone and offers to take him to safety.
Hopefully it involves an attitude adjustment!
My time is at an end.
He then heads off to a meeting, leaving the detonator in Kellys capable hands.
Humans think of evolution in terms of progress and advancement, spouts Eichhorst.
A rightly terrified Sanjay is given the task of putting the suitcase in place.
The crew arrives at Stoneheart with hopes of finally ending this war.
A battle commences, The Master still at full strength because something is wrong with the communication blocker.
The taking of a soul is but another blood meal, he says, taunting Setrakian.
But your suffering, this is my delicacy.
Our merry band of heroes looks stunned they actually did it.
His one-man party gets interrupted by the arrival of his wife and son.
Theres no time to catch up, as Kelly immediately rushes at Eph.
A struggle begins, the two fighting each other off as Zach screams for them to stop.
The fight does end, but only because Eph stabs Kelly through the neck, killing his strigoi wife.
Its all over now, he says, trying to console his son.
I hate you, he declares, and then clicks the button.
The explosion is instant and brutal.
Zach managed to escape the blast in good shape (if we arent counting emotional damage).
Thanks to you, we are well again.
Eph eventually makes it outside, only to realize Zach is already gone.
He stares up to the sky, which goes dark as the bomb smoke covers the sun.
The last shot of the season ends with strigoi flooding the streets.
And hopefully, somewhere in Mexico, Gus is chilling on a beach with a margarita in hand.
