Olivia gets some water for the guy, but Etta stops him, saying it'll kill him to have water. He can't have any for another three hours. And we're spared some fake bullshit-science explanation for that. In fact we're spared any kind of explanation for that.
Olivia sits there, crouched beside Gael, and Etta coldly tells her he's not worth a single tear. "Loyalists sell out their own kind like rats," she says. With Gael listening attentively, Etta says she knows her mom just woke up, but she needs to look around and see what the Observers have brought. "This is war, and we're losing," she says.
From the other room, Walter calls for Etta, and she warns her mom not to get too near the guy. Etta leaves, and Gael and Olivia stare at each other.
Outside, Walter asks for her necklace. She's not currently wearing it -- the clasp is loose, so she took it off and put it in her pocket -- and she's surprised at the request, especially when Walter says they need to melt it down. Peter assures her they just need the silver for solder and she pulls off the bullet and hands it over, then looks at the bullet in her palm for a moment.
In the other room, Gael wryly asks Olivia how he looks, and she says, "Like you're in pain" but not sympathetically. She rejects his warning that his absence will be noticed by saying she doesn't believe anyone's coming for him -- he wasn't there because they were seen or triggered some kind of alert, but because -- Olivia pulls the breadcrumbs out -- he came to feed the birds. And since he's probably not even supposed to be here, this will be the last place anyone would look. It would also be the last place anyone would look, because they'd find him there and thus stop looking.
Olivia leans in to speak conspiratorially to him, adopting the Good Cop role in the classic Good Cop/Batshit Cop dynamic, and urges Gael to tell Etta what she wants to know before he ages into the colostomy bag years. "You must have something to live for. I'm trying to help you," she says.
