The human engineers were not up to the task of shades of gray needed for true human emotion, which is why Ford created Bernard.

Bernard isn't taking what he did to Theresa well. Ford wants him to straighten up and fly right, erase all memories of their involvement in Theresa's disappearance and then Ford will erase his memories of the event.

Maeve wants to be fixed, programmed to be allowed to the leave the park and to get the explosives out of her spine that will keep her from doing that. Frick and Frack don't seem to want to do that. Blond dude wants to brick her.

They find Theresa's body and Ford is pleased it was her who was trying to sell secrets to someone. Sad she fell and died, though. Charlotte agrees Bernard should be reinstated. The two are playing a game.

The Man in Black recognizes the woman who used to welcome people to Westworld. He thought she was retired, but he guesses Ford never loses use for a pretty face. The more he taunts Teddy, the more Teddy remembers, including The Man pulling Dolores by the collar of her dress.

As a result of that memory, he punches The Man in the face. He's not supposed to be able to do that.

Dolores, meanwhile, is acting more human as William gets angrier and less compassionate. She sees her body in the river, but it's a memory.

Charlotte goes to see the story dude. She's telling him that the end all be all villain Ford is creating is called Wyatt.

Sylvester thinks Maeve was put to sleep. She shows him what they've been tinkering with by slicing his throat. Felix fixes him with the doohickey used to fix her. Huh.

Whatever they did to Maeve, she can not just speak and the hosts listen to her, doing exactly what she says. She's a storyteller.

Bernard asks about the differences between him and Ford, and he also asks if Ford has ever made him hurt someone like he did Theresa before. When Ford lies to Bernard, Bernard recalls killing Elsie.

Poor Dolores doesn't know which end is up. She makes it to the old town where she lived, where they trained hosts to dance and such. She recalls hosts dying and almost shoots herself before William comes to get her. She thought for sure Arnold would be there.

They come upon a union search party...and Logan is riding with them. 

Charlotte takes dumbass story guy down to the body basement. She uploads what Theresa was trying to steal into Dolores' original father and wants dumbass to get him out of the park. They picked the wrong dude.

Stubbs talks to Bernard, but he's surprised to learn there wasn't a relationship between them. I think Stubb's days are numbered.

The Man in Black reveals who he is. Sort of. He came back after his wife died to see if he was truly evil, so he followed his own story. He killed Maeve and her daughter just to see what he felt. Then, just when he thought it was done, the woman refused to die. He felt nothing, until she tried to carry her daughter out in the dirts and fell. That's when the maze revealed itself to him. 

Ford's game doesn't allow for Teddy to kill. But Arnold's game allows for the hosts to cut deep. To give us what our sorry little lives lack, meaning. To give our actions consequences.
