Preview trailer and promotional images for the Arrow episode "What We Leave Behind"

The CW has just released a trailer for the December 7 episode of Arrow which is titled “What We Leave Behind.” But before we get to the trailer, how about some preview images?

The episode is the midseason finale of Arrow so big things are probably going to happen, especially when it comes to the Prometheus storyline. Here’s that trailer; the promotional images released by The CW can be found below. There seems to be some development with the Evelyn storyline within!
