After taking weeks of hiatus, "Arrow" season 4 is back with an all-new episode, titled "Canary Cry."

Synopsis for the episode suggests that moving on after the death of Laurel will not be easy for the members of Team Arrow.

"The team struggles to deal with Laurel's death. Diggle is especially overwhelmed with guilt over choosing to believe that Andy had changed. Meanwhile, Lance refuses to believe his daughter is gone," says the synopsis.

The next episode follows the members of the team as they mourn the death of Laurel and try to move on with their lives without their dear friend. They know pretty much that they do not have all the time in the world to mourn, knowing that Damien Darhk is still on the loose.

Meanwhile, the conscience-stricken Diggle is most desperate above all to cook someone's goose, especially now that he already knows about his brother's close connections with Damien Darhk. He is buckled down to seek revenge for Laurel, no matter the cost.

While Diggle takes retribution for what happened to Laurel, Lance finds himself in a blue funk, still in denial that his daughter is gone. "Canary Cry" follows the disconsolate father as he reaches out to Nyssa, asking her to help him bring his daughter back.  

As for Oliver Queen, it is hard to tell if she is already prudent enough to map out a sensible plan to deal with Darhk.

"Arrow" season 4, episode 19 airs on April 27, 9:00 P.M. on The CW.
