Okay, so Philip seems to have figured out how the US has made their planes 'stealth.' They have apparently painted a bunch of iron balls and affixed them all over the aircraft. The paint absorbs (?) the radar, but also makes you sick. Philip spoke to the guy who worked on (figured out?) the project and he's dying of cancer. And all the bats that were in the area died also. He seems to believe he was poisoned on purpose. But, I don't think that's exactly the case.
With the bug now back in Gaad's office, we've discovered that the FBI now knows that Emmett and Leanne were KGB. This causes Elizabeth and Philip to become concerned for Jared, so Elizabeth heads over to see what he knows. She asks him what the FBI spoke to him about, but he's a little vague. He does tell Elizabeth that he was shown pictures and drawings of people who his parents might have associated with. While not overly concerned, Elizabeth isn't 100% sure he didn't recognize her.
She ends up following him after her leaves the house and he goes to a diner to meet Kate. Elizabeth is concerned because Kate did nothing to disguise her appearance and just showed up at this meeting as is.
And speaking of Kate, we can't get in touch with her (or George, who it took me a while to figure out is probably the message relaying guy that Larrick killed). Turns out, Larrick has broken into her house, attacked her, and tied her up. He's gone through her stuff and found her radio signals. He's insistent that she tell him where the people are who killed his friends. But she refuses and he kills her. But not before she can leave a message for Elizabeth and Philip.
The two of them head over to the house to make sure that all is okay as no one has heard from her. However, when they show up, both her body and Larrick are gone. So, they still don't really know what happened. But, while searching the house, they find a hidden, coded message that just says, 'Get Jared Out.' Do we think that Larrick is going after him next?
Meanwhile, the truth about Nina has come out. If she cannot convince Stan to give her the stealth technology (now that he's in love with her and his wife is potentially having an affair), she'll be sent back to Russia and tried for treason. And if found guilty (which she will be), I'm sure they'd kill her. Oleg tells her that if she doesn't think she can get him to turn, she should run.
She heads over to talk to Stan about it. She tells him that she can't go back, they are going to send her back to Russia for treason. With no idea what to do, she breaks down to Stan. He assures her that he will make sure she's safe. They are in this together and he won't let anything happen to it. I have no idea if she's playing him, or serious.
Also, Elizabeth decides to let Paige go and protest nuclear weapons (which seems way more dangerous than a church group, but it's only a day). It was a little annoying that she didn't even bother to consult with Philip on this; just made a snap decision on her own about it. But, she seems to think Paige is like her, she's just had her energies focused on the wrong thing.
