The visible countdown built on Abigail's icebox may be a great bit of visual storytelling, but it implies Elliot Sadwick was aware she was dying when he took her in, and went through the trouble of building her a customized icebox. For the first part, this makes it a bit odd he'd accept her as security, since the family has as much reason to want to keep her in the box as to get her out; and for the second part, it seems uncharacteristic of the old heartless Jerkass.
