Gundam Wing Episode 23
Sally and the resistance fighters hire ex-Alliance deep-sea specialists and find Wing where Heero had left it. They fight off OZ soldiers who are there as well, and Sally comments that the gundam will help their cause.
In space, Duo is at a spaceport on the colony where he's been recovering. OZ has targeted the gundam pilots for assassination and Duo is trying to get to the Moon Base without being caught. He's approached by a young OZ recruit, Hilde Schbeiker, who tries to get him to join the organization. Later, Duo uses a fake ID to get close to a shuttle that's leaving, but Hilde stops him. He fights his way into an MS hanger and steals a Leo, blasting his way out of the space port. Hilde pursues him and easily captures him in his damaged Leo. He's put aboard a shuttle to the Moon base, to be imprisoned with the other pilots. On the way, Duo talks to Hilde about why he's fighting with the gundam and manages to change her mind about him completely. When he blasts out of the shuttle and heads towards the base, she follows him but ends up allowing him to get into the facility. So much for Hilde's career in OZ.
At the base, Heero meets up Wu Fei, who has allowed himself to be caught so he can get close enough to Tsubarov to kill him. Now three gundam pilots are at the base. It becomes four when Duo, who breaks into the base to try to destroy the mobile doll factory, meets up with the scientists, who advise him to let himself be caught as they finish up his restored and upgraded Deathscythe. He does this and ends up in the cell with the rest of the pilots.
