At the hospital, a woman brings her husband Macmillan Fairfield to Dr. Schwartz and says that he needs help. She checks his chest and finds a bomb planted inside. She yells at the nearby people to run, and the bomb goes off. Across town, Deathstroke watches the explosion.
The next day at the bunker, the two teams watch a newscast about the explosion. Authorities believe Deathstroke engineered the attack.

William says that Deathstroke is Grant, and Dinah notes that Connor called Deathstroke "JJ". Diggle demands answers, and JJ finally explains that they thought JJ came back with them. In the future, Grant trains a new Deathstroke leader: JJ. William says future Star City is run by gangs, and the cops and politicians are corrupt... including Rene. He says that they tried to save the city, and JJ killed Zoe.

JJ resented it, and Connor blames himself for not being a better son. Connor calls Diggle "Dad", and Diggle points out that all Connor has done since he got there was lied before walking off.
William tells the others about how the future but the city was too big. Mia says that they should accept who JJ really is and stop Grant before he screws up everyone's future. Grant made a name for himself targeting the rich and appealing to the poor, seducing JJ. The headquarters didn't blow up in the original timeline, and it will take William time to recover the data on the drive they found.

Dinah notes that they all failed to save the city, and figures that Diggle is blaming himself. She tells Diggle that knowing what has happened will either destroy them or save them. Now that they've seen the worst, they should be their best.
Laurel and Mia go to the hospital and Laurel realizes that Mia is going to try and kill Laurel. She says that she's not a big fan of Oliver and if Mia wants to kill Grant, she should go ahead. Laurel asks why, and Mia says that Grant always escapes, making himself a cult hero. Her new partner explains that she talked Felicity out of killing Ricardo, and Felicity never regretted changing her approach so maybe Mia should try doing things differently as well.
Later, William tells Oliver that Mia is back. William figures that Oliver is brooding over Mia leaving. He says that Mia makes mistakes, and Oliver admits that he abandoned Mia to go with the Monitor.
