When Kilgrave gives an instruction that can be interpreted in multiple ways, how free is the recipient to select an interpretation? Does the recipient always have to choose the most lethal meaning?
When Kilgrave escapes from the sealed room, he tells Trish to put a bullet in her head and the intention is clearly that she should shoot herself, which she tries to do and is saved by the fact her gun is empty. When Jessica returns, Trish is trying to push a bullet through her temple; Jessica makes her put a bullet in her mouth instead, and then points out to her there is now a bullet in her head, which seems to be enough to resolve Kilgrave's compulsion.
It seems that where a command can be ambiguous, any literal interpretation would be valid enough that, if carried out, the recipient considers themselves to have fulfilled Kilgrave's instruction.
