Season 5

Plot
The season opens up with a snippet from Lucy and Messer's relationship, just them playing in the park with Hedgecliffe. The loving memory fades away, cutting to the stark reality where Lucy is driving a car, injured from her battle against Winter and Jefferson, with a dying Messer lying in the backseat. Not knowing where else to go, Lucy drives them to Oliver's house, honking as she tears into the frontyard and destroys his vegetable garden. Oliver comes running out of the house, initially angry at Lucy but then stopping when he sees her covered in blood. He helps her to carry Messer inside, and they lay him on the bed where he immediately begins attending to his wounds with his medical equipment. He calls his sister, Clara, who soon comes from the hospital with blood bags. Meanwhile, Lucy sits on the lounge, and slowly closes her eyes, passing out again due to her head trauma.

She awakens to the sound of Monty kicking open the door, gun in hand. He aims it at Lucy and shouts for Oliver, and Lucy quickly grabs her gun and points it at Monty in return. Oliver comes running out, attempting to de-escalate the situation. Monty informs Oliver about the attack on Headquarters, and that it was caused by Messer's rebellion and that Lucy has been helping them ever since Tranquility. Lucy shouts that this isn't true, and tries to convince them that Jefferson and Winter have teamed up - something which appears unlikely due to their very public feud. Desperate for Oliver to continue working on Messer, Lucy puts down her gun and raises her palms, pleading with Monty to believe her. Monty swears loudly and profusely before putting down his own gun, shouting, "God damn it. You better not be lying to me, but I can't see two of my friends die, not after everything else."

Oliver runs back into the bedroom to help Clara with Messer, and Lucy collapses onto the ground, gagging for air. Monty grabs some bandages and helps stitch up her shoulder, and gives her some medicine for her head - stating plainly that he knows a few things since he's been helping Oliver with his exams. They sit on the floor of the bathroom after Lucy has been stitched up, and she tells him everything that happened between her and Winter. She hesitates before revealing that Messer killed Luke in order to prevent him from shooting her. Monty is horrified about the news, but still trusts in Lucy and Messer. Lucy asks about Max, who she learns is still at Winter's side and is in a blind rage against Lucy and Messer - he believes that things will be worse when she learns about Luke's death, since he was like a brother to her.

Meanwhile, we see Helios recovering from the attack. They have regrouped at one of their smaller safe houses, where they assess the number of dead. Max and Winter are together, and we see that Max is angier than ever. She truly believes that Lucy and Messer have betrayed them. Winter is busy with trying to organise attacks against the Rebellion, protection for Helios sleeper agents, and also to cover up media investigation. While this happens, Max searches for her friends. One of the tech support gently pulls Max to the side, and reveals that Luke's body has been recovered from the wreckage with a gunshot wound to the head - caused by Lucy and Messer. Max doesn't believe it at first, until the woman admits that in the few seconds of footage they have recovered from the Data Cloud, they can see Messer shoot Luke. Max demands to see the footage herself, and when the woman refuses, becomes uncharacteristically violent toward her. We see Max watch the footage, and a growing look of pure anger spread across her face. When it ends, she tells the woman to "play it again".

We cut back to Oliver and Monty's house the next day. Lucy lays next to Messer in the blood-soaked bed, holding his hand as she sleeps. Oliver and Monty are having an argument about what to do in the kitchen, as Helios will be coming to their house soon to check their "safety", and will know something is wrong as soon as they see the stolen car, but Messer is in too weak of a state to be moved. Lucy enters after overhearing their conversation, and suggests that they find the rest of the Rebels. Monty doesn't think it's a good idea as he still has greviances about the group, but they end up agreeing. With Messer passed out and unable to provide coherent conversation, Lucy and Monty go to his hideout to find clues as to where the Rebels may be.

Fortunately, Helios' numbers have been desimated by the attack, so no one is at the hideout. The place has been torn apart previously by other agents, and Lucy and Monty pick through the remains. Lucy fortunately knows Messer well enough to find a USB and a burner phone in a hidden compartment. They plug the USB into Monty's laptop, but the data is encrypted. They plan on returning to Oliver when they notice two agents outside. They quickly hide as the agents enter, and overhear them talking smack about Messer and the Rebels, though they admit to having no idea where the hideout could be, and being unable to gain much information from what they took from the hideout - so they have returned for a second look.

Back at the house, Oliver is in the middle of strapping Messer onto a gurney when he sees two agents pulling up to the front of the house through their security cameras. He quickly wheels Messer out the back door, his heart pounding and hands sweating. As the agents enter the house, Oliver realises he has no means of escape while also safely bringing Messer along with him, so he enters the house and tries to casually greet the agents, resulting in him almost getting shot through the head. Oliver tells them that Lucy brought Messer here to try and save his life, but it was too late and Messer died on the operating table ("bed"). Afterward, Lucy went insane and tried to kill Oliver, but he was saved by Monty - who has just chased him out of the house.

The agents appear to believe him at first, but become suspicious when they see Messer lying on the gurney outside. One of them approaches despite Oliver's protests. He tells Oliver that he will need to be taken with them to see Winter, and that he will handcuff him until they know he can be trusted. Believing that Messer is dead and that Oliver is so weak that he doesn't need to be immediately retrained, he turns his back and begins to call into headquarters. Oliver tries to convince him not to, when he hears Messer whisper, "Duck." Oliver turns around and realises, and immediately drops to the ground while Messer shoots the agent with the gun Lucy left him. The other agent comes running out, but ducks back in when Messer shoots at him. He quickly calls for backup. Oliver grabs the gurney and runs with Messer in it, down the street and toward the park, desperately trying to escape.

During these events, we see Lucy and Monty stealthily take down the agents at the hideout. They then take their things and their car, and drive back to the house. Lucy scrolls through the phone and sees that it only has one contact number, called "Her".

Oliver tries to hide in the park with Messer as more Helios agents flood into the area. Oliver starts having a panic attack,
