Supergirl, Season 2

[Barry and Cisco appear through a dimensional breach in Kara's apartment.]

Cisco Ramon:
This better be the right place. 'Cause if this isn't the right place, someone's about to be real confused.

[Kara comes in the front door.]

Kara:
Barry!

Barry:
Hey.

Kara:
I knew it. I knew that was you. I knew that it was you and that weird space portal thing! [hugs Barry] Hi.

Barry:
Yeah. I'm sorry. It took a couple tries to get here. This is my friend Cisco.

Cisco:
Well, "friend" is a loose term. We work together. Hi. I have to say it, this is a nice universe you got here.

Kara:
Thank you.

Barry:
Okay, do you remember last year, when I helped you out and you promised to do the same for me?

Kara:
What are we up against? Story continues in Invasion! (Arrowverse).
