Get rid of him

Nyra knows Drake is playing with Christopher, before going for the kill. She is angry at him for putting her on the spot. 

"Get rid of him" she muttered to Drake, referring to Christopher, before turning away.

Christopher looked between them and he is growing agitated.

"Who is he Nyra?" Christopher asked again when she didn't answer him the first time.

"None of your business" she snapped at Christopher.

Originally she planned to lock herself in her room and let Drake deal with Christopher and her grandmother. She knows she is acting like a coward. But she trusts Drake would deal with everything thankfully.

She would never accept it in front of him, but he is much calmer and collected in stressful situations like this than her. She would become anxious and angry, but he would remain calm and collected.

So she decided to leave him to that task. She would go and hide in her room until then.
