Echo: Hi, Whirlwind
 
Whirlwind: Oh, hey. Didn’t know you were here
 
Echo: Mmhm. So where were you today?
 
Whirlwind: Just out… doing fun stuff
 
Echo: Who with?
 
Whirlwind: ……………….. You know don’t you? You sneaky little filly scruffs up Echo’s mane
 
Echo: smiles
 
Whirlwind: So yeah, I was hanging out with Hot Head
 
Echo: I thought you liked Prism though pouts
 
Whirlwind: Echo, we broke up for a reason…
 
Echo: But you still like him
 
Whirlwind: As a friend, yes! He’s a great friend! He’s funny, and caring and affectionate and… shakes head He’s a good friend. But just….. not a coltfriend. Relationships don’t always work out, y’know?
 
Echo: Why?
 
Whirlwind: Well, he was nice to me but he’s still growing up and he can be a bit of a show off. I just didn’t really like that about him and didn’t want to have to deal with that all the time…. and relationships don’t always work out, y’know?
 
Echo: Then why didn’t you go out with Hot Head?
 
Whirlwind: Because, he’s… a lot like Prism. I admit, he can be quite a gentlecolt but I’m not sure if I could handle the arrogance again…
 
Echo: Aaaaand you still like Prism?
 
Whirlwind: What’s with all the questions? Jeeze, nosy much? giggles Look, relationships are just complicated and colts are dumb so I’m taking a break. That a good enough answer for you?
 
Echo: shrugs I guess.
 
Whirlwind: But hey, now that I don’t have to worry about boys, I get to spend more time with my favorite cousin! hugs Echo
 
Echo: Actually, I’m hanging out with Icy today
 
Whirlwind: gasps Do you have a crush on him~?
 
Echo: Ew! No! He’s like my cousin!
 
Whirlwind: chuckles What are you talking about? No he’s not
 
Echo: Well, Aunty Rainbow and my mom are basically sisters. So he’s like my cousin. So is Prism
 
Whirlwind: Oh…. wow… Never thought about that
 
Echo: Yeah. Well, I’m gonna go. He’s teaching me some tricks and stuff. Maybe you can teach me more when I come back!
 
Whirlwind: Alright then. Have fun and be safe!
 
Echo: Okay! Bye leaves
 
Whirlwind: Heh, cousins. I guess that makes sense………… but wait…………. I’m her cousin too……… what does that make me and Prism……….. shudders Ugh, nope! I’d rather not think about that
 

 
So, I guess Icy and Echo being “cousins” kinda depends on your head canon about Rainbow and Scootaloo’s relationship XD
