Although they initially shield themselves, they then see that their Pokédexes, which they gave up at the Team Galactic HQ, have been returned to them. The Grunt refers back to his decision to quit Team Galactic, and redraws his account to suggest that the three Lake guardians convinced him to quit, as he remembered that the Pokédexes, which remained with the Grunt, were sacrificed for the Lake guardians' freedom.

Suddenly, the Grunt is struck down from behind. Pearl looks behind to see that it is the same black shadow that knocked down his father, and the Grunt, being tended to by Platinum, replies that it is, who used to be owned by the woman that controlled his body. The Grunt claims that the woman released Darkrai into the Distortion World because it was too difficult to control. He remembers the nightmares it brought to Pokémon and humans wherever it went, and this statement is met with Charon's maniacal laugh.

Charon claims that the Advanced level Grunt couldn't control Darkrai merely because of who he is: a Grunt.

He is immediately met with resistance from Platinum, thus orders his to use, but Platinum's full team of six pop out to block the attack. Diamond and Pearl are relieved to see Platinum with a full team for once, but then notice how each member appears to be breathing more rapidly.
