Lincoln: "You know what would be really inappropriate? If I started flirting with you right now."
So he does. And they do. And Cappie is like a foot away, smoldering with all this random rage out of nowhere, and it's so stupid. But not as stupid as...
Lena: "I just know your Dad's alive."
Lincoln, verbatim: "My mom's been saying he's alive for months. But somehow when you say it, it feels true."
Yeah, as we'll learn, that's because she's suddenly got psychic powers that make her bite her tongue off in the middle of REI. But also, what a stupid thing to say to a person, that you would never actually say.
...I'll let Lincoln break it down for you:
Lincoln: "Looks like they were looking for a cure to cancer. They were looking for a specific gene sequence in the [Secret Angel People]. They managed to isolate part of the variant gene and recombine it into a retrovirus. When it was ready, it was meant to act as a cure."
They cut open a Boiunatic and talk about his sexy youthful cardiovascular system, and that's when -- as Linc says -- things go bad.
Lincoln: "Based on no information whatsoever, I have decided this was their head of security."
Kurt: "(That is a good guess.)"
Hana: "Hey, guys."
Scientist: "Awesome, good. Hana, could you drive this Cure of Cancer to somewhere?"
Hana: "No! Instead I will gun down all of you, and then shoot the virus!"
So she does that. Shoots that virus. And then -- "The sample's still reactive!" -- everybody starts turning into zombies. So it was the five doctors and Hana that became zombies, and then they ran around eating everybody else. Which is like 60 people, not including Rabbit and (obv) Emmet.
AJ: "Kurt! Even though you have a gun, hate me, and clearly are not on the up-and-up -- and just saw your fiancee turn into a zombie -- I am going to hassle you about your overall agenda!"
Tess: "Hey! Somebody's signaling us across the Quad!"
Rabbit: "Shiny mirror. Coming from the infirmary."
Tess: "[see above]"
