Abraham Stern (No. 100)

The penny returns and moves from criminal to criminal in a memorable 100th episode of the series, which is anything but serious and ever so entertaining because of it.

Lane and Spader worked very well together as their characters are similar in many ways, and both actors excel at portraying criminals of this sort. I won't give anything away, but I love how Red's own agenda and the interest of the bureau align once again, even though they want different things.

I was also impressed by Keen in this episode. Her confrontation at the end of the last episode was clumsy, and the way she masked it showed why they need Kaplan, but she has shown to be resourceful in rectifying her mistake in multiple ways. I like her darker side as we've seen it since the passing of Tom.
