A major catalyst of the Abigail homestead coming to a halt is Daniel Salazar.
Ofelia wakes up with him, and as they run away, she begins to express some discomfort.
He isnt the only one haunted by loss, however, during the finale.

It takes the reassurance of her new convert, Nick, to calm her.
She gives them all a deadline of the following sundown to leave.
(More on that in a bit.)
She asks Nick and Alicia to gather supplies before they head back to the boat.
He shall be responsible for their actions, allowing them to stay with that one rule.
Except for Strand, that is.
She wants him gone in a time that she sees as a beginning, not the apocalypse.
Despite Celias protests, Strand spends much of this day toiling away and digging a grave for Thomas.
Madison also comes to visit him after a particularly discouraging discussion she has with Nick.
She confronts him about how hes changed.
This fascination with the dead worries her, though he has bought into Celias line of thinking.
Theyre not dead, and theyre not the infected, as Madison tries to label them.
Not wanting to further agitate him, Madison simply says shes trying to understand.
And so Nick tries to explain, though with a disturbing line of thought.
He believes nothing can touch him.
He recalls being on the beach, coming face to face with a walker and coming away fine.
He felt no fear or hate in that moment, only the belief that he wouldnt die.
I move among them, Mom.
And Celias flock seemingly holds onto her words and beliefs just as much as Nick does.
She promises them the world is being reborn and that all of their sins are to be forgotten.
What does this new world of hers look like?
He calls the dead walking among them abominations.
(Interestingly, she calls them my dead in this scene despite insisting previously they are not dead.
But she knows it is those who have long stopped walking that are keeping him such a frazzled state.
Madison comes to Celia as she cleans the bed on which Thomas died.
So the de facto leader of the household brings Madison to her chamber containing all of the walkers.
She unlocks the gate, stepping inside with Madison to survey them in close proximity.
And Madison would do just about anything for her children, including killing Celia.
So she steps out of the gate and locks it as Celia looks on.
Yet Celias assumed demise is only the start to the chaos that is about to ensue.
This vision of his wife questions him for not burying her, promising shes still waiting for him.
He and the show flashes back to the origin of it all.
Given a gun as a child, Salazar has to kill a man in the river grasping to life.
He reaches out for the young Daniel, but Salazar shoots him dead.
Yet, this vision of his wife tells him that man wasnt his first victim.
Salazar himself was the first, lost in the horror of this action.
He finds his way to the locked up walkers after Madison has locked Celia in there.
And though she doesnt find Travis, she discovers Nick walking back toward them.
Unfortunately, he fails, but not because he cant find either of them.
He discovers Travis on the side of the road, far away from the Abigail estate.
He eventually stumbles on a seemingly abandoned building, until he hears a noise inside and goes to investigate.
And thats because he actually can speak English.
Madison may need him, but so does his son.
Nick lets them be, returning just in time to find the Abigail home on fire.
Madison pleads with him to come along to the boat, but he refuses.
