Lust had kicked up a fuss for as long as she could and there were claw marks on the inside of the coffin lid. She hated it and hated that her death was caused from a lack of food and water. So ugly. She lasted longer than a mortal would but her body was still human and did wither and die. It took days for her to come back to life and Sin or not, dying was not a picnic. Her brothers would have felt it.. well, Gluttony would have. Greed had been too busy being a real boy and would have missed his sister's demise.
She'd only come back to life recently but by being trapped in that box, she was effectively cut off from all desire and Sin. It made her more mortal than she cared to be. But her nasty attitude was there, because that lovely personality she had was all hers naturally. She waited with gritting teeth as she heard Satan outside the box. She couldn't wait for it to be opened.
