(In the future, Supergirl is seen waking up from her bed. Then she realizes that she is in the watchtower, much for her confusion. Then she sees Zatanna and Constantine hanging out. Then she keeps walking as she is approached by Blue Beetle.)

Blue Beetle: Good morning, Kara. Late start.

(Supergirl chuckles as she keeps walking. Then she sees Green Lantern talking with The Flash.)

Green Lantern: Have a nice day, Barry.

The Flash: Thanks, Hal.

(Then she sees Green Arrow having trained Firestorm.)

Green Arrow: Good job.

Firestorm: Thank you.

Green Arrow: Very good job.

Supergirl: Oliver...

(Then she sees Superman and gets confused about it.)

Supergirl: Kal?

Superman: (turns around to see Kara) Hey, Kara.

Supergirl: (approaches her cousin) Kal...

Superman: Are you okay?

Supergirl: You're here.

Superman: Where else could I be?

(Then Nightwing (Dick Grayson) comes in)

Nightwing: Hey Clark. Hi Kara.

(Supergirl gets impressed by Dick Grayson knowing her name and tries to touch his face. But then Starfire grabs her hand.)

Starfire: Whoa.

Supergirl: Easy, Kori.

(Nightwing and Superman chuckle.)

Nightwing: Well, some things never change.

Supergirl: It's good to see you, guys.

Superman: Uh-huh. (to Supergirl) Bruce is waiting for you.

Supergirl: See you later, Kal.

(Then thr three leave as Batman turns around to see Supergirl.)

Supergirl: Batman.

Batman: Kara, is is everything all right?

Supergirl: Well... yeah... I think...

Batman: You did it.

Supergirl: Did what?

Batman: Kara, don you have something to tell me I don't know?

Supergirl: Perhaps.

Batman: I'm not used to trust people, but I guess I can help you.

Supergirl: Thanks, Batman. I could really use some help.

Batman: Help with what?

Supergirl: Pretty much everything after 1973. I think the history I know is a little different.

Batman: Welcome back.

Supergirl: It's good to see you, Bruce. It's good to see everyone.

Batman: Well...

Supergirl: I had a promise to keep.

Batman: You and I have a lot of catching up to.

Supergirl: Yeah.

Batman: What's the last thing you remember?

Supergirl: A different planet.

(Back to present, Kevin is seen having a date with Team RWBY as Supergirl narrates.)

Supergirl: The past. A new... and uncertain world. A world of endless possibilities.

Yang: I'm so happy I have a date with my baby brother.

Blake: We four are happy.

Supergirl: Countless choices define our fate. Each choice, each moment... a ripple in the river of time.

(Kevin and Team RWBY are seen in the movies.)

Ruby: Why do we have to go to the movies?

Weiss: I won the bet, remember?

Supergirl: Enough ripples... and you change the tide.

Kevin: Girls, the movie is about to start.

Supergirl: For the future is never truly set.

(The End)
