I saw that a couple months ago. My friend showed it to me. I think I read a bit to much into the video. It made me really sad cause of how touching the characters were to each other. No one will even give you a dollar today let alone their own arm.

Same. Well, the sad part anyway. It actually took my second view of the vid to realize it was her arm. But it makes me think, and I would probably get the answer if I watch the vid again, but was she left handed?

No, she used her right arm to draw. But he lost his left hand. So she gave her left arm to him. [[ someone is ambidextorus! ]]

So he is the left handed one! Thanks for clarifying ^,=,^
