ZZygarde (Z2)
[in it's 50% Forme, speaking telepathically] Greninja, I've come to ask a favor of you.
Was that the voice of Zygarde?
ZZygarde (Z2)
The vines that reappeared, the roots have burrowed themselves deep into the ground, and they emerge by absorbing negative energy. What we destroyed was merely on the surface. The scars from the incident that nearly destroyed the world are deep! The two of us are destroying the roots that are scattered throughout Kalos one by one.
SSquishy
[telepathically] However, it's difficult for even me to pinpoint their exact locations, yet, Greninja, it seems that you are somehow able to locate them.
GGreninja
[in its Ash-Greninja form] Ja. [Yes.]
[gasps, then remembers the negative energy from the evil roots] So that was the negative energy...!
ZZygarde (Z2)
I do not know why only you possessed that power, but I am in need of your assistance.
SSquishy
Will you help us with your power?
BBonnie
[Gasps as Ash walks up to Greninja, which is now faced with the decision of its life.]
What'll it be, Greninja...?
[Greninja turns around and closes its eyes in a serious manner.]
[solemnly] I know. What happened before can never happen again.
[Greninja nods to Ash.]
Remember what Professor Sycamore said?
[A flashback of Greninja taking Pikachu's deflected Electro Ball to keep Pikachu healthy as a Froakie plays out, followed by the scene where Ash rushes to Sycamore's lab with it barely conscious in his arms.]
That maybe... it wasn't a coincidence that I met you way back when you were still a Froakie. I think that maybe, he was right. It wasn't a coincidence.
[Flashbacks of Froakie evolving into Frogadier and later defeating Anistar City Gym Leader Olympia play.]
That when you and I power up, it isn't an accident. Maybe your power was always meant for this moment.
[Flashbacks of Frogadier evolving into Greninja, battling Sawyer's Sceptile, and saving a Spewpa in the Winding Woods, followed by it and Ash shaking hands, play.]
Thanks. You always became stronger to help someone else. So now this time, you'll help Kalos and the world!
It's like something's telling you that what you need to do now is find all that negative energy! Don't worry! We'll always be connected, even we're not in the same place!
The truth is, we won't ever really be apart.
This is what you've gotta do!
GGreninja
[nodding its head in understanding, realizing the future of the world of Pokémon lies in its hands] Gren.
[It walks up to Ash and extends its arm out, then Ash and Greninja clasp hands and embrace.]
[emotionally] Oh, Greninja...
GGreninja
[emotionally] Greninja...
[Serena, Clemont and Bonnie watch on distraught as Greninja turns away from Ash and walks towards Squishy and Z2.]
[with tears in his eyes] That's right. This is how it has to be.
GGreninja
Greninja. [It extends its arm to Squishy.]
SSquishy
[telepathically] Thank you.
[to Ash] Ash, Greninja will be in my care.
Yeah! I'm counting on you, Squishy!
BBonnie
[concerned about the future of her and Squishy's friendship] Hey, Squishy...?
SSquishy
We probably won't see each other for a while, Bonnie...
BBonnie
[almost breaks down crying, but is suddenly cheerful through her tears] It's okay! I know that you've got a lot of important work to do! I'll always be cheering you on, you know?
SSquishy
I'll always be with you too, Bonnie.
BBonnie
I'll come and find you when I become a Trainer! We'll be together again, that's a promise!
SSquishy
Yes, that's a promise!
[Dedenne and the rest of Ash's Pokémon express their farewells to Squishy, Z2, and, most importantly, Greninja]
Take care of yourself, Greninja!
BBonnie
You too, Squishy! Take care!!
[Greninja holds Squishy in its hand and looks back as it leaves Ash and his friends]
Greninja and Ash may be parting ways, but this also means the beginning of new encounters! In search of their own new encounters, our heroes will no doubt experience many new and exciting adventures, as the journey continues!
[Dedenne, not wanting to say goodbye to Ash, Serena, and their Pokémon, has run off, sending the gang in a chase around Lumiose Airport. Using Pikachu's electricity, they find it hiding behind a conveyor belt's TV screen.]
[concerned] Pi... Pika-pika!
[startled] Ne... Ne-ne-ne?!
BBonnie
Dedenne! Dedenne, come out! I'm begging you!
[in protest] Ne... Ne! Denne! Dene-nne!
BBonnie
Dedenne, you've just got to come out here! Please?
Denne-denne! [breaks down crying]
BBonnie
I know why... Dedenne doesn't want to say goodbye to everyone.
[coming out of hiding] Dedenne... Dedenne! [jumps emotionally into Bonnie's hands]
[apologetically] Denne-ne-ne-ne...
BBonnie
Hmmm... [nuzzling Dedenne] It's okay~...!
[Everyone walks toward Bonnie and Dedenne.]
Dedenne, you can help Bonnie make her dreams come true!
You'll see! We'll battle!
I know I'm gonna have to do my best, or you'll beat me!
None of us wanna lose to you!
[All the Pokémon voice their agreement.]
[Bonnie and Dedenne laugh.]
Congratulations! Your Ultra Class ranking has risen to ninth.
Thank you so much! [Both Ash and Drasna shake hands]
But it won't be quite so easy to climb higher in the rankings.
Yeah, but I'll do my best! [Pikachu also agrees with the statement]
Sirfetch'd and Dracovish are simply charming. I'll know that I'll cheer for you!
Now don't neglect your training!
[Bonnie is seen staring right up at Drasna. Wonder what this could mean...]
BBonnie
I have made a decision!
[She gets down on one knee and holds her hand out to Drasna on behalf of Clemont, continuing her running gag from their initial journeys through Kalos.]
Drasna, you're a keeper! Please take care of my brother!
[Everyone freaks out.]
[who seemingly missed this] Pika-Pikachu!
BBonnie
I mean, Drasna? You're so strong and in control that I don't think there's anybody else for my brother, see?
[blushing] Oh, my stars! Whatever shall I do?
BBonnie
[After getting grabbed by Clemont's arm] Wait, but why?
I told you to stop this a million times!
