Ah, the flashbacks. As is the case on the vast majority of Arrow episodes, especially since Season 3, they're the weakest part of the show this week. Although they're just kind of there, I'm still hoping they have something big planned with Reiter and Lian Yu, but it's not clear exactly what that is yet. Reiter is all ready for Oliver to be punished during this episode, until the tattoo he got from Constantine starts to glow, and so does Reiter's orb. It obviously means a lot to him, and he locks Oliver up rather than allowing Conklin to continue whipping him. He reminds Conklin that's he's expendable, which Oliver clearly isn't. But why?
