"I'm sure, and I know her. And she told me," he says. Sarah scoffs. "Just like she told you she destroyed every part we ever captured. Just like she tells us what she does every night when we go to sleep. When she comes back in the morning, she's covered in cuts and bruises. Just like she told you she loved you." Well, that last one's kind of true, isn't it? John slams the table, and snaps that his mom doesn't know anything, and he stomps off to go have a hissyfit somewhere.
"I'm thinking of an herb," John Henry tells Ellison and Weaver, who gleefully guesses "tarragon!" which is wrong, and Ellison is FINALLY losing his shit and asks Weaver what's wrong with her, why she isn't angry. "You asked me to teach him ethics, morals and rules. What good is it if he's not gonna follow 'em?" he says, and she tells him Henry will, if they give him a chance to learn them on his own, and Ellison eventually throws out an "oregano" guess, which turns out to be right, and Henry gives them a clue: "The sun is shining on Savannah." Ellison gets on his walkie-talkie to tell the security team to check near all windows. This would be the same security team that didn't notice the little girl wandering around the super-secret basement in the first place. And John Henry is now thinking of an animal, so Weaver and Ellison yell animals at him until Ellison says, "Bird!" which is right, and is also the clue, which confuses Ellison at first, until he has a eureka moment and radios security to meet him at the elevator.
And they head up to the roof, where they find Savannah asleep inside the company helicopter. Again: nice work, security team! I suppose the answer is John Henry guided her everywhere and yadda yadda yadda, but you'd think Weaver would have a little bit more sophisticated security measures to counterbalance John Henry's abilities. Anyway, Savannah climbs down into Ellison's arms, and he passes her off to Weaver. "You found me, mommy," she says, sleepily, and Weaver is all, "Yes, I did!" and carries her off, Ellison watching them. Probably all pissed off that Weaver's taking the credit.
Over at Riley's foster parents' place, now, and the foster dad answers the knock at the door to find John standing there, which must fill him with all kinds of happiness. "Is Riley around?" asks John, and Aaron says she didn't come home last night, and John pretends to be surprised by this. After a moment, Aaron invites him in. "Foster kids. That's the way it is with them sometimes. They drift into your life, and then they drift back out again. Not always according to plan." Then he starts talking about Riley being a tough cookie: "Good heart, as I'm sure you know, but tough to know," he says. John says he needs to talk to her, so maybe he can leave a message, but as he's saying this, the phone rings. Aaron answers it, and is relieved to find out it's Riley. John looks rather surprised. Too surprised, in fact, considering that this turns out to be the damn plan.
