At first, Mina could not understand why her sister was so worked up over President Lee coming to warn her. Of all the things the man had done, it was the only one she could tolerate and while she knew it was done to garner favor, it was still helpful. Sadie had in fact filed for her own death, forging her father's signature on documents before she married Troy.

It was physical at first, but after some time, he moved her onto poisons, which, oddly enough, was the beginning of his end.
