Updated the previous scene of Thrawn slightly. To continue:
The Resistance fleet falls out of Hyperspace inside a dusty pink and blue nebula, Tantive ships and carriers surrounding their captured Destroyer like minnows. The Falcon undocks from the Tantive IX and shuttles over to the Destroyer.
Ben, Finn, Kalonia, and much of the Tantive crew march down the halls where Resistance fighters are escorting First Order troops into the main hangar bay. Ben sports a new prosthetic leg and arm, his saber at his side. In an anteroom, Poe and Rose voice their concern for this stage of the mission. The Resistance is barely able to contain this many prisoners and Poe doesn’t trust that Ben has had a change of heart. Poe jokingly says that they might have to just open the hangar to space. Rose looks at him in a ‘don’t even joke about that’ way. Finn tells Poe that Rey believes he has changed, and Finn trusts her. Poe asks where Rey is, anyway. Finn evasively says that she is still recuperating from her ordeal. Poe finally decides to trust Finn and Rey on this, so he lets Finn and Ben through to a balcony overlooking the hangar.
On the balcony overlooking the assembled officers and soldiers, Ben arrives to a holo broadcast of Hux declaring himself the new supreme leader. Ben cuts off the video and announces that the First Order has betrayed them and is their enemy as well as his. He names Hux and Thrawn specifically as leaders who will suppress all religions of the Force under their fist and in so doing bring disorder to the galaxy. The soldiers cry out at this, but Rose pulls up the video of Thrawn destroying the city of Amma, telling them that their fellow soldiers were betrayed and murdered in this cold, calculating blood. The soldiers quiet down. Ben continues. He says that as one who was dead and returned to life, he has seen the reality of the Force present in all people, not just those of noble blood. He is no more worthy of command than another. He bequeaths his title and authority to Finn, the man who slew Kylo Ren. Henceforth, he wishes to be known only as Ben. Finn takes this solemnly and the soldiers salute him. He motions this down. His first order to them is to remove their helmets and see their fellows for who they truly are. They fight for the First Order no longer!
…
Ben wanders through the secondary hangar of the Destroyer, inspecting the TIE fighters in their racks and his own modified TIE racked close to the Falcon on the deck. From that ship he hears cries and sounds of banging metal. He turns to the Falcon and enters its darkened interior. Crates and tools are strewn everywhere. He sees half of Luke’s lightsaber lying amid the scattered trash and he picks it up. Rey sits cradling the other half in the middle of the cargo bay, shaking. Ben tries to console her, saying that even Luke couldn’t heal a broken crystal with all his powers. Rey says that she must heal the crystal, that she must resurrect the Jedi Order, that she must make Leia proud. Ben tries to tell her that perhaps their powers might not return, that the texts could be right. Rey says that Ben is clearly wrong, for the Force is always with a person. It is inconceivable that it would simply betray her. Ben disagrees, but admits that he is no expert on the mysteries of the Force. There were others at Luke’s school, he says, that were far more knowledgeable.
A Porglett wanders over from its nest, roused by the commotion. Ben picks it up with his good hand and gives it to Rey. He says that all life is connected by the Force, and that she is no more or less important than any other, and to gracefully accept these changes as the will of the Force. Luke tried to teach him that, but he wouldn’t listen. He feels that Luke was right that the Jedi should end, and he was right that the Sith would never again return. He sees how the galaxy is now controlled by those entirely without the Force, and that perhaps this is its will as well. Rey recognizes that Ben’s near death experience has changed him, but she says bitterly that it has made him give up. She leaves the Falcon for the Destroyer bridge and her friends, the ones who will still fight.
…
The bridge is a hive of activity. The former captain of the vessel and his officers are showing many Resistance officers the controls. The captain is in conversation with Finn and Poe when he is drawn away by the insistence of an officer. They go to a corner to converse quietly together. Finn and Poe survey the crews in the pit and look out at the blue and pink clouds surrounding them.
Suddenly a shout goes up in the pit, and an officer points out the viewscreen at a TIE fighter flying off into the clouds. Finn whirls and asks which soldier had gone rogue. An officer replies that they’re checking the registry now. Rey walks onto the bridge and replies that it’s Ben. Poe asks if he’s running away, and Rey says it wouldn’t surprise her. Finn turns to Poe, asking what he as Admiral will do about this. Poe replies that he leaves this to Finn as captain of this vessel. Finn orders the launching of the TIE interceptors to go after Kylo. Officers scramble to alert the crews, who are not at all ready for this test. The former captain and the officer are unperturbed by this event and start manipulating the controls of a computer terminal in the darkened corner of the bridge.
Another shout goes up, this time about two unknown objects approaching them from behind in the nebula. Finn pulls up an overlay on the viewscreen to visualize the new threat and orders the ship to turn about. Poe barks orders for his Resistance ships to follow suit and go into a delta formation on either side of the arrow-headed Destroyer. The shapes resolve themselves as Destroyers, and Finn and Poe both shout ‘Thrawn!’ in unison. Finn orders shields up, double front. The Destroyers continue to close distance as Poe scrambles Resistance fighters into action. These launch and begin to fan out in front of their fleet just as Finn’s TIEs finally begin to launch and fall in behind them. Poe barks that one of these Destroyers will have a Hyperspace tracker, and to prepare the droid controlled transport for a Holdo Maneuver.
Suddenly a new group of signals appears from behind their fleet, coming from the direction of Ben’s escape. The shapes resolve as TIE bombers, and before Poe or Finn can react they launch a blistering array of missiles directly toward the unshielded aft end of the Destroyer. There is no time to alter shields, and everyone braces for impact. A second passes, then another. Rose dares to open her eyes, which had been shut tight in anticipation of disaster. Poe realizes that Finn has taken his hand in panic. They disengage with an embarrassed shifting of eyes and clearing of throats. Suddenly the bridge is rattled by the passage of Ben’s TIE fighter sweeping its wings inches from the windows. The radio crackles to life. Ben’s voice appears on the com, dryly stating that their ship has been blown to atoms. Poe stares in confusion and starts to ask how Ben could have controlled that simulation from a TIE, but then sees the former captain and his officer nonchalantly leaning against a console in the corner. The former captain adds that their Holdo Maneuver wouldn’t have worked either, since the First Order fleet has officially phased out such active trackers after their weakness became apparent. They give a salute to Ben, who continues flying circles around the Destroyer’s bridge giving the Resistance a good dressing-down. This is Thrawn’s modus operandi, Ben says, drilling and testing his crews every spare minute of the day, and it’s what the Resistance will need to do if it wants to survive even a minute against him.
