Edwin comes along with a supply of gear apparently requested by Walter, who announces that he's going to build a suit that will allow them to go into the mine. Judging from the arm he ripped of the corpse, they'd need skin three-hundred layers thicker than a rhinoceros's to do so. Well then, I'm sure Science MacGyver here can cobble together a suit that's as protective as three hundred rhinoceroses from stuff found around a camp of refugee treepeople. "I need you to go back to the van because I need the weather-stripping," he tells Peter and Olivia. Yeah, that should do it.
Just as Peter and Olivia leave, Etta gets a call from Anil, warning her that they got a call from one of their operatives. "The loyalists are tracking you. You've got to move," he tells her.
Peter and Olivia are pulling out the van's weather-stripping and haven't been told the news about the loyalists despite being RIGHT THERE when Anil called. Peter asks Olivia if he upset her when he was talking about the restaurant, since he knows she never forgets names.
Of course not, you lummox. Olivia remembers it was Donovan's. "It's not that I can't remember. It's that I can't forget," she says. She asks if he remembers that when they couldn't find Etta that day, he drew a plan on a napkin. He does.
With flashback scenes illustrating for us, Olivia describes how Peter was talking about going up to Maine to a refugee camp he'd heard about, and even though Olivia was nodding, she was looking past Peter to the wall of missing-person flyers outside. "With every day, the odds of finding our little girl the way we wanted to find her were getting worse, and we didn't talk about it," she says.
And then there's this: she felt responsible. This floors Peter, so Olivia explains that she wanted so much to be a mother, but she just didn't think she was "programmed" that way. I don't know that we saw that feeling very much from her, but I do buy that sentiment.
Ever since she the Cortexiphan trials, she has felt at odds, that she was destined for something else. "So how could I have this incredible little girl? So, when we lost her, I felt like that was my punishment, my punishment for being too conflicted to appreciate her when we had her," says Olivia.
Peter is wisely letting Olivia work through her feelings on the subject, because Olivia's not done yet: That day at the restaurant, Olivia says she knew she had to go back to New York because she didn't want to find what she knew they were going to find. She believed that Etta was dead and she didn't want to see it. That's why hearing Peter say that she went back because of her strength and Etta talking today about how she admires Olivia, has been gut-wrenching for her.
