It sounds to me like she had laparoscopic surgery. They make three small incisions and look at you from the inside with a camera. It's usually used for surgery regarding ovaries, the uterus, fallopian tubes, or digestive disorders.
She has never fully come out and said "Tom and I lived together in Japan. There was another room we shared and that whole room was fake."
She said the room was decorated in her fake style, but not that she pretended to live alone and not have a boyfriend. When you consider how long they've been dating and we've only actually known about him for two-ish years...that's a lot of deceit.
It was about time, tbh. They've been dating for 6 years and are both of appropriate marriage age (Elbow-san a littler more than Taylor). Taylor is also the only unmarried girl in her family and it seems as thought Elbow-san's sister is married as she has children.
Also, I know her assistant is learning but holy moly, the camera work in this video was baaad. The whole time Taylor was talking to Moonie it was like the camera was floating on waves. Up and down, back and forth, side to sideeee. Taylor has steady cam equipment, why isn't she using it?
