Ali: We have yet another dare. cuckooclock222 dares the Gaang to meet their older selves. And Nico (I think the one from PJO/HOO) has to come.

Zuko: Who's this Nico guy?

Ali: Someone from a different fandom.

*Ali waves her hand and old Aang, Katara, Zuko, Sokka, and Toph comes. Nico appears too.*

Nico: What am I doing here?

Ali: Quit being so grumpy. We need you.

Nico: Fine. It's just I need to get back soon.

Ali: Is it because of Reyna?

Nico: Maybe... Wait how do you know her name?

Ali: Because I do. Anyway, cuckooclock222 wanted you here. 

Nico: OK.

Ali: Well, you guys need to meet your older selves. 

*The young and the old converse.*

Korra: Hey Katara!

Old Katara: Hello.

Young Katara: Wait, you- we- know her?

Old Katara: Oh yeah. I helped her before. *Old Katara has a sparkle in her eyes.*

Young Katara: Cool!

Old Aang: Hey little me!

Young Aang: Hey old me! *whispers* Did I marry Katara?

Old Aang: Yes we did.

Young Aang: YES!

Young Toph: I'm awesome!

Old Toph: Yes we are! 

Young Sokka: Why aren't I old like the others?

Old Sokka: Because I think we died early. I'm not sure.

Young Sokka: How can't you be sure?!?

Young Zuko: I certainly got uglier the older I got. 

Old Zuko: We did, didn't we?

Ali: Yeah you did. I'm glad Young Zuko is here and not his old self. OK, say bye to yourselves!

Young and Old Gaang: Bye!

*Ali waves her arm and they leave but Nico stays.*

Nico: Why am I still here?

Ali: Because cuckooclock222 wanted you here for a couple more dares.

Nico: Man.
