Phantom pain
Phantom pain is a painful perception that an individual experiences relating to a limb or an organ that is not physically part of the body, either because it was removed or was never there in the first place
After I decided to remove one of Hope's arms, I immediately thought about this topic. I want to say that, naturally, the sensation from the limb is not always as painful as I comically show. (Although, it can be so unpleasant)
Usually in such moments Lamb tries not to show it, after all they have experienced pain and worse. But sometimes this pain can overcome even warriors like Hope.
