Okay: so the peach tree is actually Beni and Momo’s ship, which Washuu needs in order to set everything straight. They start the start-up process as Yuki tries to hack into the warhead. They’re confronted by troops, but Touri, Hana, and Hachiko take care of them. When more arrive, Kurihara orders a retreat, warning the girls to get as far away as they can.
Something tells me with Washuu on their side, they won’t have to worry about anything going BANG, at least in this situation. When Beni gets the ship started, Tenchi and Momo finally ‘synchronize’ in the same time, much to Momo’s tearful delight. Some progress at last!
