WHAT DO YU THINK ABOUT JENNA?

For some reason I dont think Jenna is fully blind. How would she know what color her lipstick is. and when she was putting it on she was looking into her reflection. A blind person wouldnt have done that. How does she be finding different locations and knowing who is talking. She has been gone for a 년 she cannot possible remember everyones voice.
Another thing that was werid to me, at the lunch 표, 테이블 she was talking all nice about Alison. About how she came to see her in the hosptial. But in the hallway she was like "whisper whisper almost feels like alison is back". So had she become 프렌즈 with alison 또는 still hated her ?
