"Sure, let me just get you a change of clothes so you can wash your dress." Making sure that Brittany stayed put, as it really wouldn't do any good for her to wander into Dave's room on accident as Tina didn't know how that would work out, Tina went to her room and found something that was close enough to Brittany's size and style and returned with the change of clothing to the living room.
"Follow me." While Tina knew it wasn't hard to get lost in the apartment, she knew better than to put anything past Brittany. That would just lead to all sorts of problems. Mostly because who knew what sort of trouble the cheerleader would get herself into. Really, it was a miracle that Santana hadn't snapped at the blond. That took patience. And love. Oh, Tina was not blind. She had a feeling that Santana was in love with her best friend. She might not have been from the time where the Latina had figured it out, but her coming out and seeing how patient she was with Brittany while giving no one else the time of day? It was obvious.
Pushing the door open to the bathroom, Tina stepped aside.
"Here you go. Towels are clean. Turn the knob towards the red for hot water, blue for cold. Adjust as needed." Smiling to Brittany, Tina left the bathroom and headed her laptop. Might as well let Santana know that Brittany was there lest she incur Santana's wrath at keeping such information from her.
