[Oliver watches a recording of Thea killing Sara]

Malcolm Merlyn:
I don't think you want the league to see that. And if you kill me, they will.

Oliver Queen:
This isn't her.

Malcolm Merlyn:
You ever heard of a plant called Votura? It grows in South America. In facts, it thrives in Corto Maltese, making the subject extremely susceptible to suggestion, or retaining no memory of their actions.

Oliver Queen:
I will tell Ra's this was you, that Thea was under your control.

Malcolm Merlyn:
And he will still kill her. She fired the arrows.

Oliver Queen:
You have given her a death sentence.

Malcolm Merlyn:
No. What I've done is given you incentive.

Oliver Queen:
To do what?

Malcolm Merlyn:
To tell Ra's that you killed Sara Lance. By right, you'll be given a trial by combat - with Ra's. His death will erase any blood debt from his reign, including Thea's.

Oliver Queen:
And yours.

Malcolm Merlyn:
I have to be honest - it was my concern that the whole killing thing would have been a deal breaker for you. But, uh, I'm gratified to see that Thea is still sufficient motivation. Don't take too long making up your mind. Ra's isn't known for his patience.
