Apparently the squinty killer Alpha from last week has been a busy beaver, and Red Flag leaders are dropping off the grid. Perhaps these two facts are connected? The team tracks Squinty to his next target, who turns out to be none other than Dr. Rosen's own estranged, apparently strung-out daughter, Danielle. And she's an Alpha. Surprise.
Rosen's got his hands full now. On one front, Danielle is taking him on the Guilt Grand Tour of his failings as a father and a husband, while not being particularly forthcoming about the significance of the necklace she stole that Squinty was trying to recover before Cameron killed him. On the other hand, Agent Sullivan is haranguing Rosen to figure out what Red Flag's big plans are for seven the next morning, so that's pretty time-sensitive. Fortunately, one problem solves the other, as Rachel figures out that the necklace carries an encoded message, inviting Red Flag's senior management to a big meeting at an abandoned brick factory.
But I should tell you who's calling the meeting. While the above is going on, Bill has a wild hair up his has about "Stanton Parish," that clue he was given two weeks ago. With Gary's help, he learns that Stanton Parish was a scientist whose pro-Alpha manifesto laid the foundation for Red Flag before his death 30 years ago. Only Parish isn't dead. In fact, he's been alive since the Civil War, without having aged a day. And Rosen figures that this Alpha-Alpha is the one who called the meeting.
So the next morning, as the team and Agent Sullivan and a small army of tactical agents are about to move in on said meeting, Rosen realizes that Parish, who hasn't shown, is using them to get rid of certain members of Red Flag who want to go public, including Gary's friend Anna. He tries to stop it, but is as effective as always, which is to say not at all. The raid goes off, and it's a bloodbath, with Cameron facing off against a fellow hyperkinetic, Bill fighting a dude with waffle irons for hands, and Gary discovering Anna's shot-up corpse and freaking the hell out, nearly getting himself killed along with all the other Alphas who get massacred in there.
While Rosen and the team are feeling shitty about being used to wipe out thirty-odd Alphas, and Rosen's trying to patch things up with his daughter, he gets a private visit from none other than Stanton Parish himself, grateful for Rosen's help in keeping Alphas under wraps for the time being. Rosen declines Parish's invitation to join him in whatever Parish has planned next. Instead, he's heading to Washington DC to testify before a closed-door committee. And he uses the opportunity to broadcast (with Gary's help) an announcement to the entire country that Alphas exist. So that's a bit of a curveball. Even Parish is surprised, even though he was warned something like this might happen by his own personal expert on Lee Rosen: Danielle. The government yanks Rosen off the air, but given that there's a second season planned for next year, his radio silence probably won't last forever.
Rachel's long-distance tracking Isaac Hale, that squinty-eyed killer Alpha from last week. Even on a busy street from blocks away, she can see that he's meeting up with a young woman who seems be using her fingertips as some kind of divining rod, leading Squinty purposefully through the crowds. Apparently the whole team with the exception of Gary (remotely guiding them from the office) and Bill (presumably dead from that heart attack that felled him at the end of the last episode) is out in the field, connected via walkie-talkies, and when Gary sends Dr. Rosen a real-time security-cam video feed of Squinty and Dowsy making their way through the neighborhood, Rosen makes the genius leap that she's an Alpha too. Well, he's the expert. Cameron, following Rachel with Nina, makes the even more impressive deduction that Dowsy's the tracker and Isaac's the killer. During this tense moment, Rachel exposits for no organic reason that Red Flag leaders have been disappearing all week, and Rosen responds that they need to keep eyes on Isaac but not engage. Which means there will shortly be some engaging.
Meanwhile, a ratty young woman in a hoodie and her seedy-looking boyfriend pass a pawn shop, where he tries to convince her to sell something for money. They're both looking rather strung out and in search of their next fix. She refuses, and soon they encounter Isaac, who's making his Alpha-fist as he says they have something of his. Suddenly a dramatic wind kicks up, pulling petals off all the nearby flower vendor displays as though there's a Dementor in the house. The young couple runs for it, only to get cornered in a blind alley. Isaac asks them not to make him kill them, because it makes him tired and cranky. And think about how they'll feel. Rachel overhears this from however many blocks away, and leads Nina and Cameron in a sprint to catch up. By the time they get there, Isaac has already delivered the young man's Death Of A Thousand Veins. Cameron leaps off a van, knocking Isaac over before he can kill the girl, but too late to save her boyfriend. Rosen arrives along with the rest of the team and recognizes the girl: "Danielle?" he quavers through the chain link fence. She doesn't seem happy to see him at all, to the point where she makes a break for it, via some exit that didn't exist a moment ago. Rosen quickly tells Nina to Push the girl, but when she tries, Danielle grabs Nina's wrists and debilitates her with glowy pulses of light from her hands, then runs away. Rosen sends Cameron and Rachel to go after Isaac while he chases the girl. Still crouching over his sort-of girlfriend, Cameron asks Rosen what's so special about Danielle. Well, she broke Nina for one thing, but Rosen has another bit of news before he takes off in pursuit: "She's my daughter." Figures.
