"My girlfriend got one of the letters," Oliver says, thinking back a few months ago to when Felicity had gotten a letter directing her to hurt someone in exchange for a chance to see home again. It'd been something they had talked about extensively before experimenting with and Oliver knew others had gotten the same choices. Mark seems right about this one, though: it doesn't seem anything like a choice.

"I wonder what happens if people who aren't on the list go and help? I mean, obviously we'll send the ones they told us to," Oliver says, evaluating that list again. "But what happens if I go too? Or someone else you know? Is it going to screw up the whole thing or is it just additional firepower?"
