[You are Rainbow Dash, you can be female or male!]

You all are on a boat, other people are talking and drinking juice, or exploring. Applejack is seasick, so he's/she's puking on the side of the boat. Fluttershy is helping Applejack, Rarity is also with Fluttershy and helping. Twilight is with Pinkie and Sunset... No one realizes you aren't there until Pinkie says...

Pinkie: "Hey, where's Rainbow?"

Twilight: "Yeah! You're right. Where is he?"
