Also did JZ had a prothestic or both his legs are fine because I do understand that he doesn't want to burden…
He meet her and was standing up before she left so I am not sure if he pretended and hid it from her so she doesn’t worry and just leave. A little confused with the writing there. From what I see he has both legs but his spinal cord is damaged so he needs intense rehab, still wondering how he stood up when he meet her.
