Who does Ms.Emma ask for help in order for this to happen to Jefferson

She asked Grant

At her request, Grant visits Miss Emma. Miss Emma knows Grant lied about his previous visit to Jefferson, because her own visit was disturbing: Jefferson asked her if she had any “corn for a hog,” asking viciously and repeatedly until Miss Emma grew so distressed that she slapped him. Grant is irritated, feeling once again that he cannot help Jefferson and stating that he will not let Jefferson make him feel guilty. Tante Lou insists that Grant continue his visits.

Guidry is angry, and Grant finds out later that his anger stems from a visit Miss Emma paid to Mrs. Guidry, during which she asked if she could meet with Jefferson in the dayroom or in some other large room so that she could sit down. Grant denies Guidry’s accusation that Grant encouraged Miss Emma to make the request. Guidry asks Clark and a “fat man” named Frank what he should do. Clark declares that Jefferson should remain in his cell, Frank declines to answer, and Guidry decides to ask Jefferson what he would prefer. Still, Guidry says, even if Jefferson gets to go to the dayroom, he will have to be in shackles.
