Ray Palmer:
...Why aren't we dead? Not that I'm complaining.

Malcolm Merlyn:
Oliver was vaccinated against the Alpha Omega virus five years ago. An associate was able to draw a version of the vaccine from his blood.

Ray Palmer:
A synthetic skin graft.

Malcolm Merlyn:
Upon our incarceration, I was able to vaccinate each one of you cutaneously. I saved your lives. I believe the words you're searching for are "thank" and "you."

Felicity Smoak:
Okay. Assuming this is all some part of a double double cross or a triple cross - I'm losing count - your master plan still has one major flaw, we're still chained in a dungeon.

Malcolm Merlyn:
Patience, Miss Smoak. All we have to do is wait.

Laurel Lance:
Wait for what?

Malcolm Merlyn:
The thunder.
