Meanwhile at the hospital, Diamond and Pearl are with all of the injured Gym Leaders injured, most notably Crasher Wake. Diamond gives Pearl a music player that Crasher Wake gave the nurse to give to Pearl. The music player has a theme song for Pearl, that Crasher Wake promised to make him. Pearl begins to cry, and then quickly apologizes. The two of them then decide to check on Platinum's Pokémon, who are supposed to be being healed by a famous doctor. They meet Daisy Oak healing the Pokémon and Bebe, who suggests that once the Pokémon are healed they should be placed in a box for Platinum. Daisy questions whether Platinum has the skill necessary to handle the gift Pokémon from Gym Leaders, and Pearl vehemently defends her ability as a Trainer. Following this, Diamond and Pearl leave to make an appointment with someone they don't know.
They meet with a man that they don't recognize, who seems to know them. However, when he puts a statue in front of his face, they remember him as the voice that spoke to them during each of Platinum's Gym battles, and that his name is Chairman. The Chairman reveals that three of the Elite Four of Sinnoh have been working on the Charon memo and that they decoded it with the help of Professor Oak. Diamond questions where the final member of the Elite Four is, and the Chairman informs him that they don't always work as a team. They then put on their new Pokétches and set off. The Chairman begins to follow, to their confusion. They decide to take him and Dr. Footstep along, creating a quartet.
At Battle Arcade, Platinum has just finished her 20th battle, with the next one being against the Frontier Brain Dahlia. While attempting to stop the roulette on paralysis, a shock goes through the earth and jolts her so she can't press the button within the time limit. Dahlia then gets the right to stop the roulette, and stops it on the Swap tile. The Trainers have to switch Pokémon. Platinum and Dahlia then trade Pokémon.
