Jessica walking away had a faint smile on her lips. The night has been fruitful. She didn't expect Desmond to come to the balcony—making him believe she was genuinely uncertain about Davis's fate, that she was probing for answers because she lacked confidence in his recovery.
That was exactly what she wanted him to think.
Who would wish their enemy a long life, let alone a chance to rise again? His confidence in Davis's permanent state of helplessness only confirmed what she had long suspected—he wanted Davis out of the picture entirely.
The more he assumed Davis was doomed, the less cautious he would be. He would slip, make mistakes—mistakes she could use to her advantage.
Desmond might have planned well but like the old man said she will remain an unknown factor in this battle of wits. Her naivety will be her best trump card.
