Griseous Orb

After the encounter with Team Galactic, the gang visited Angie at her family's Pokemon day care center in Solaceon Town. They were just about to leave but Ash stopped everything and took out his Master Ball.
"What's wrong Ash?" Dawn asked.
"Please be quiet. It's Mewtwo. He's contacting me to tell me to go to the Solaceon Ruins." Ash said.
"Mewtwo may have news for us." Brock added. "We better get to the Solaceon Ruins."
Once they got to the ruins, Mewtwo was outside waiting for them. He held a weird yellow orb in his arms.
"What happened Mewtwo?" Ash asked. 
'I informed Giratina about Team Galactic and their intent to use Dialga and Palkia to create a new world by destroying this one.' Mewtwo said. 'Giratina was not happy to hear this and then I said you needed it's help.'
"Did Giratina agree to help us fight Team Galactic when we need it." Ash said.
'It did and it gave me this. The Griseous Orb.' Mewtwo said.
He held the orb up.
"Hey I've seen this orb before." Ash said. "Back when I was still in the Reverse World. Giratina used this orb to recover after it had been injured."
"That must mean this orb is connected to Giratina like the Adamant and Lustrous Orbs are connected to Dialga and Palkia." Brock said.
"Wow, who knew Giratina would have it's own orb." Dawn said.
"So it's obvious we will need this orb to summon Giratina when we need it to fight Team Galactic in the event they do summon Dialga and Palkia." Ash said.
He remembered last time and took it from Mewtwo's arms.
"Good work Mewtwo." 
"Can I rest in the Master Ball for a while?" He asked Ash.
Ash then returned him.
"Okay guys, we have Giratina's orb the Griseous Orb as proof he'll help us. Remember we never tell anyone about this until the time is right. Agreed?"
"Agreed." Brock, Tomo and Dawn nodded.
Ash then put the Griseous Orb in his backpack and then he and the others got ready to leave Solaceon Town again. 
To him it was history repeating itself, but on a much different scale.
