Ty stammers "I wish the wall was back to normal!" The color returns to the wall, and it is once again opaque.
Dusty's head started to hurt "You were... to me? But I'm your broth- sis-... ow..." Dusty grabs her head and falls to the floor as a wave of pain and confused emotions crash into her. Her two genders were fighting. She just found out that her brother is sexually attracted to her and was watching her in the shower. And she has no idea what just happened to that wall, that seems to violate her very perception of reality and the laws of physics as she knows them. But above all else, of all of these feelings, one rang out the loudest. And that was pure, unbridled rage.
"D-dustin?" Ty says wearily while pulling his pants back on.
Dusty growled. "Why are you calling me that?... Why? How do you know?"
"Dusty! I mean Dusty, my voice slipped, that's all!"
Dustin pulled himself up from the floor. "Is that why you did this to me? So you could fucking jack off to me?" He has decided which version of himself was real, and was systematically killing every girly thought and suppressing every girly memory he could find in his war torn brain.
"I- I wish- I wish that I-- uh..." Ty tries to form a wish, but the words just get stuck in his mouth.
"I'M YOUR FUCKING BROTHER YOU PIECE OF SHIT! I'LL KILL YOU!" He charged at Ty with murder in his eyes.
"I WISH YOU WOULD STOP!" Ty screamed.
Dustin stopped, he froze completely. Now a living statue in the middle of Ty's room, his hair still dripping and his breasts still heaving with rage.
