Starcrossed Part 3:
The episode begins with Hawkwoman being arrested by the thanagarian lieutenant. She is brought before Commander Talak, who is hurt by her betrayal. S much so that he punches his lieutenant on the face, before ordering him to attack the League at once.
The League studies Hawkwoman's data, and Batman tells them to split efforts. Half of them will work on deactivating the shield protecting the warp generator while he and the others will proceed to destroy it.
Wally: What will you do? Throw a boomerang at it?
Bruce: Something like that.
The Thanagarians attack Wayne Manor (knocking Alfred out in the process) and invade the Batcave. The League (in costume) puts up a far better fight. Batman uses his bats to best advanage and all that.
Superman, Wonder Woman and Green Lantern head to the thanagarian command ship to turn off the energy field, while Batman, Flash and J'onn head to the Watchtower in a thanagarian vessel (J'onn reads the mind of the lieutenant in order to learn how to fly the ship).
Team 1 (Supes, WW and GL) head to the mothership and hundreds of ships start attacking them.
WW: This is so unfair.
Superman: Yes. They don't stand a chance.
Team 1 fights more efficiently than ever, mowing down entire fleets of starfighters.
Meanwhile, Team 2 (Bats, MM and Flash) inflitrate the occupied Watchtower and knock out all thanagarians, J'onn and Flash place them on an escape pod when Batman suddenly closes the pod and jettisons it toward Earth.
Batman: Gentlemen, it's been an honor.
Batman stays in the Watchtower and pilots it towards the warp generator.
J'onn warns Superman, who flies desperatedly towards the falling Watchtower.
Meanwhile, GL blasts a hole in the mothership and finds his way to the field generator. Thalak is there, waiting for him.
WW releases Hawkwoman.
WW: I should let you stay there for what you did to us.
Thalak breaks the power ring and pounds John into a pulp. He is saved by the arrival of Hawkwoman, but she is knocked unconscious as well. John gets up and tricks Thalak into hitting the field that protected the generator switch. Kalak is knocked unconscious and John and Shayera press the switch together.
Batman is unconscious from the reentry as the Watchtower is about to crash on the warp generator, but Superman rescues him and the warp generator (and the Watchtower) are destroyed.
Wonder Woman keeps on battling hordes of thanagarians until Thalak tells them that the mission failed and they must head home. Shayera will never be allowed on Thanagar again.
In the aftermath, the Leaguers are voting to see if they will expel Hawkwoman. But before they tell her their decision, she quits the League. While the League renews its commitment to defend the Earth, John (with a broken arm) says farewell to Shayera, who leaves for parts unkown, while John silently sheds a tear.
