Was convinced I had accidentally thrown out Spider-Woman's regular right hand. Completely emptied a storage bin looking for it and no dice.
Got Jocasta in yesterday and I temporarily placed Jocasta's spare hands onto a white shelf. And hey, there was Spider-Woman's hand at the exact same spot on the shelf, haha.
Thanks Jocasta, you're a neat looking figure and you helped me find Spider-Woman's hand!
