Quotes 

• Brainiac-5 : Alex and Nia were right. Behold, the May 25, 2009 Midvale Weekly.

  Alex Danvers : Huh.

  Brainiac-5 : The week of Midvale High's prom.

  Nia Nal : The same night as the Aquarid meteor shower.

  J'onn J'onnz : This is where we need to go to save Supergirl?

  Alex Danvers : Yeah, I was back from Stanford on vacation. I just dropped Kara off at the school assembly hall for prom, and, uh, with a jacket. It was oddly cold that night, and that's when the shower hit, and then this giant meteor just came bearing down and Kara flew up and punched it out of the sky.

  Nia Nal : But the meteor had kryptonite.

  Alex Danvers : The impact was enough to destroy the meteor, but Kara got pretty hurt. She fell through the roof of the gym.

  J'onn J'onnz : No one saw her?

  Alex Danvers : It was under construction, and when I found her, her hand was all cut up. It was the first time I ever saw her bleed.

• J'onn J'onnz : How specifically do we get to this place in time?

  Brainiac-5 : Well, based on my survey of satellite imagery from 2009 and the trajectory of the meteor, I was able to predict Kara's point of contact. After running those figures through 3-D modeling, I produced a rendering of the debris field, and by overlaying that with geologic radiation emissions of that same night, plus Kara's own biological markers, I was able to pinpoint the exact location of Kara's DNA.

  [Alex stares blankly] 

  Brainiac-5 : The high school's baseball diamond center field. Nia and I depart after I gather my things.

  Nia Nal : Alex, what's this business about "the luckiest town in America"?

  Alex Danvers : When I left for college, Kara and her boyfriend Kenny appointed themselves the town's Scooby-Duo. They were saving cats from trees and kids from wells, that sort of thing, and the, uh, town got quite the reputation.

  J'onn J'onnz : I thought Kenny Li was killed when you were in high school. The sheriff was running a drug ring, and he got caught up.

  Alex Danvers : No, that's one of those old world/new world differences. In this world, Kenny never got killed.

  J'onn J'onnz : That suggests there could be other differences. Maybe I should come with you.

  Brainiac-5 : Absolutely not! As anyone who's ever seen "Back to the Future" knows, in 2009, you or you

  [pointing to J'onn and Alex] 

  Brainiac-5 : could both run into your past selves and thereby disrupt the continuum of space-time. The only people who can go on this mission are Nia and myself.

  Alex Danvers : Okay, fine. But you're going to my past. Don't. Mess. It up.
