Synopsis
In a courtroom, the accused Leaguers are asked by one of the magistrates if there's anything more they would like to offer to the tribunal before they reach a veredict. Icon rejects the opportunity, claiming that they have already presented enough evidence to prove his clients innocence. The Leaguers are found guilty on all charges, by the High Court, and are taken away. Hawkman watches from the crowd his spouse being taken away, but she just looks at him while smiling. After the Leaguers are taken away, Miss Martian, Superboy and Adam Strange arrive on court with holographic evidence of the Light and the Reach admitting that they framed the League, which would prove their innocence, unfortunately they are too late.

On the Reach's ship Black Beetle expresses his desire to leave the meat infested planet, but the Scientist point's out that the infestation is already aboard ship. Black Beetle claims that since the ambassador is gone, he's now able to kill all the heroes.

Aqualad, Blue Beetle and Green Beetle arrive where Black Beetle and the Scientist are. Green and Blue Beetle take down every Reach agent and the Scientist with their staple guns, while Aqualad takes on Black Beetle. They exchange some blows, Black Beetle using his scythe blades and Aqualad his water sword, but Black Beetle uses his chest sonic cannon and takes down Aqualad. He then turns his attention to Blue and Green Beetle. Using his telekinetic powers Green Beetle smashes Black Beetle to the ground and then holds him up to try to reset his scarab to set him free. Black Beetle claims that freedom is overrated and turns the tide using his own scarab to destroy Green Beetle's, something that would have killed him if he wasn't a martian.

Back on Rimbor's courtroom the Tribune says that the evidence that Miss Martian, Superboy and Adam Strange brought is compelling, but the High Court have already ruled. Icon tries to convince him by stating that what they have there is a confession that solidly places blame of the attack on Rimbor on the real criminals, the Light, and that it also gives the motive, bringing Earth to the Reach's attention. The Tribune agrees, but, to Icon's surprise, asks them for something "more" to offer. Superboy intervenes by claiming they do have something "more" to offer, and Miss Martian tries to help him. Since they really don't have something "more" to offer they start making things up as they speak. Miss Martian says that it is a court of justice and whatever decision they take will have repercussions throughout the galaxy, and Superboy adds that what they offer is an oportunity to demonstrate that truth and justice prevails there. Not surprised, the Tribune claims that that's not the "more" they are accustomed to receive. To which they respond by saying that if the tribunal demonstrates it's fundamental fairness, then more disputes would be brought to it, and the more disputes that are brought, the more "more" the tribunal will receive.

On the Reach's ship Black Beetle is about to strike the finishing blow on Green Beetle, but Blue Beetle intervenes. Angrily Black Beetle blames Blue Beetle for the Reach's debacle, and tries to destroy his scarab. While on the process of destroying the scarab, he and Jaime Reyes claim that they stopped fighting over control and are now friends, before turning Black Beetle's attack against himself. Black Beetle's scarab is destroyed, and Blue Beetle learns about the Reach's plan to destroy the world to erase all evidence that the Reach tried to take over the Earth.

In a park, two Reach drones come out of a lake with a Magnetic Field Disruptor, or MFD, and activate it. A black thunder cloud then appears over the city.

A huge black cloud appears over the Eiffel Tower, with six twisters appearing around it.

A huge thunderstorm appears over the city, with a drone guarding a Magnetic Field Disruptor in a monastery.

Captain Atom, Blue Beetle, Nightwing, the Atom and Aqualad discuss the ongoing chain of natural disasters, while the League is spread thin saving lives across the globe. Blue Beetle claims that this is all due to Black Beetle's Magnetic Field Disruptors scattered across the globe. The disruptors are causing a deterioration of the Earth Magnetic Field, which in turn is causing all the natural disasters. Blue Beetle locates 20 Magnetic Field Disruptors, each protected by Reach drones, which uppon reaching "crysalis" mode, will cause a deterioration of the planet's magnetic field that would destroy the world.

An incoming call from the United Nations Secretary General Tseng turns out to be, to Captain Atoms surprise, Lex Luthor. Luthor contacts the League to offer them a possible solution for their problem. Although skeptical the League hears him out. Lex claims that LexCorp has developed an anti-Reach software, a virus that disables the Magnetic Field Disruptors.

While waiting for the Tribune's decision about the acused Leaguers Miss Martian tells Superboy that she's sorry about what happened with their relationship, as it was her fault, and that she knows it's too late because he is dating Wendy Harris now. Superboy, surprised, tells her that he's not dating Wendy, that they are just friends, and that she is dating Marvin White.

The Tribune reachs a veredict, to drop the charges against the League, and they will be freed. Very excited Miss Martian jumps and hugs Superboy, Icons thanks them and tell them the League owes its freedom and reputation to them and the Team. Superboy and Miss Martian then Zeta back to Earth.

Continuity

 * The trial against the League, which was last seen in "War", is concluded.
 * Miss Martian and Superboy present the evidence the Team gathered in "Summit".
 * Miss Martian thinks Superboy is dating Wendy Harris; she made that assumption based on what Nightwing told her in "Intervention".
 * The arrival of the Team at Mount Justice mirrors the scene in "Fireworks" where the Justice League arrives at Cadmus Labs. This was also used in "Revelation" and "Happy New Year".
 * Impulse takes up the mantle of Kid Flash, following the conversation he and Wally had in the previous episode.

Trivia

 * Number 16:
 * There are 16 timestamps. Ten of them show 16 minutes.
 * When the scarab notifies Jaime of Kid Flash's impending death, he has only 16 seconds to live.
 * James Arnold Taylor replaces George Eads as the voice of the Flash.
 * Nolan North replaces Miguel Ferrer as the voice of Tribune, though Ferrer does provide voice work for the episode, as Vandal Savage.

Unanswered questions

 * What is the Light planning to do with Darkseid?
 * If the Reach apocalypse was averted, what caused the destruction seen at the end of "Bloodlines"?
