When you think of October you think of one thi- two thi- three thi- okay, whatever, October has as many as several immediate connotations. The point is, is that one of those things is costume parties! Chanda loves parties and she loves dressing up. Ellie likes both of those things slightly less, but that's okay because what she does like is Chanda and if Chanda tries hard and believes in herself she can get Ellie to go along with what she wants. Most of the time. Ellie put her foot down about Chanda's first idea, which was matching Slave Leia costumes. Also her second idea, which was a Slave Leia costume for Chanda and sexy Han Solo for Ellie, on the grounds that it will be after dark in late October in New England and the weather gets kind of cold, actually. Which is a fair point. Chanda will just buy the Slave Leia costume secretly and hide it for a special occasion.
Her third idea, which she was pretty proud of actually, was for them to go as Rey Starwars! And they don't even have to be actual twinsies, one of them can be light side Rey and the other can be dark side Rey! Chanda is able to sell this with only a token struggle from Ellie, mostly because they both agree that Ellie being dark side Rey would be pretty hot. The costumes are pretty simple, almost normal clothes, but Chanda was able to source some pretty sweet lightsaber toys that have collapsible light-up blades that don't look entirely ridiculous. One blue for Chanda, and one red for Ellie. Ooh, she's so excited.
