"A matter handled before coming here." Very simple, matter-of-fact. "But good to know, about death." Because the idea of Zelena appearing here places a dark cloud over him every time it comes to mind. An instinctual clench of his insides.

But he also knows he doesn't trust himself.

Most people who know him here do not appear to have the worst opinions of him. That would drastically change.

Because he wouldn't just kill her. He would keep doing it until it bored him.
