Dark times are coming to CW’s Arrow after the loss of Laurel Lance a.k.a. the Black Canary as Green Arrow and his team continues the war against Damien Darhk who is getting ready to unleash Project Genesis in the last few episodes that is left of the fourth season. The CW has released official promotional images for the 20th episode of Season 4 titled “Genesis” which is an indicator that we’ll finally be getting some answers to what the mysterious project is all about. It also appears that the Diggle brothers will be clashing big time as Andy Diggle was partly responsible for the death of Laurel in episode 18 “Eleven-Fifty Nine” when he betrayed the heroes and revealed that he has been on Darhk’s time this whole time. In addition, the network released an extended trailer to “Genesis” which shows even more how the two will clash.
