As Viola looks at the girls dorm an idea hits her. She can just take off her Sebastian costume that she's wearing and shower in the girls dorm as herself, Viola. Why didn't she think of this before!
Surely none of the girls would know absolutely everyone on campus so if anyone asks she can say she's been going here all along and that they just hadn't seen her around before.
Viola goes back to her dorm and quickly changes into some of her girl clothes (wow, did that ever sound weird to her) that she had hidden under Sebastian's sweaters. As she leaves the room, now in her Viola form she sees Andrew exit his room next door. He smirks and winks at her.
All Viola can think is that she's going to be sure she takes him down extra hard for that next practice. She turns and leaves before he can come over and talk to her for fear he might recognize her. She quickly heads over to the girls dorm. It's still early so she knows the showers would have very few girls if any at all. Which is good because Viola knows how crazy disorganized one teenaged girls bathroom can get in the morning, let alone one thats shared by a group of girls. The only people that would be in there now would be super fit girls who want an early morning run.
As Viola enters the building she is happy to note that the layout is identical to the boys dorm so she has no problem getting to the shower. When she gets there she notices that the showers are empty. Today is her lucky day!
As she starts to take off her shirt she hears the door open. She smirks to herself in the mirror because she doesn't have to worry about being found out this time. Then she turns to see who came in and why they haven't moved away from the door.
