Musical twin duo (Sky and Ruben) Ruben is the guitarist, piano, keyboard, and vocals. Sky is the keyboard, piano, guitar, and vocals. Ruben is a straight male. Sky is a soft butch lesbian. I got the idea for Sky and Ruben through Tegan and Sara. Her personality is based off Tegan, while Ruben's is based off Sara's. #duo #twins #skyandruben #music #teganandsara #lesbian
