What's the quickest way to cramp your band's style? Having your little sister tag along with you on tour.

In Monday's all-new episode of The Fosters, Mariana (Cierra Ramirez) is determined to secure a spot on tour with Brandon's (David Lambert) band, but her big brother is less than pleased with her new plan.

In ETonline's exclusive sneak peek, Mariana is struggling with her newest fashion accessory: contact lenses. Unfortunately for our far-sighted fashionista, the thought of poking her eye makes her nauseous.

"Speaking of things that make me nauseous," Brandon smoothly transitioned. "Matt said you want to come on tour with us. No way. That's not happening."

"You're allowed to have your option, but it's not really your decision to make." Mariana retorted before adding, "I'm prepared to do my part. I'm going to sell merch and help out with bookings and stuff. I'll be like your manager."

Good luck, Brandon. If there's one thing we've learned about Mariana, it's that she always find a way to get what she wants!

The Fosters airs Mondays at 8 p.m. on ABC Family.
