this scene breaks my heart. christine, after all, did unmask him so perhaps she wanted to see what was underneath. she just couldn’t handle it. erik, scared and hesitant, decided to put the hand that was covering his face down to see if she could ever accept him. if she could maybe get used to his deformities, and if fear can actually turn to love. but she turns around, quite immediately and completely disgusted. so erik covers his face once again, his heart breaking, embarrassed that he even tried.
