Complete story — includes the ending
Cayden James threatens to set the bomb off at midnight. Alena and Felicity are able to decode the video of Oliver killing Cayden's son, proving it was someone else and clearing Oliver. With help from Barry Allen, Oliver is able to keep James from leaving town by showing him the new evidence. James concludes that someone in his group is behind it and asks for his former allies to be brought to him or he will set off the bomb. The team brings Laurel, Diaz, and Anatoly to James, but Laurel says she was behind his son's death and her actions allow everyone but James to escape. Diaz approaches Cayden in custody, revealing that he was responsible for the death of his son and that he has the new police captain on his payroll, killing Cayden before he leaves. Cayden's flashbacks focus on his relationship with Helix, his son Owen, his arrest by A.R.G.U.S., and the news that his son was murdered.
