Germaine was literally moments away from attacking Wells before someone stepped in - another Avatar that radiated a beautiful rose coloured light and energy, despite how small and fragile she looked- one could tell she was strong, within her own right at the very least.
From memory she was Diancie's avatar, a girl named Seras.

Germaine lowered his hand from what was going to be another Dragon claw, and let her speak.
She said [color=Pink]“You’ve been gone for a long time, and by my word as an avatar, you’ll be back for a long time as well. Let’s do things better than the fools of the past.”[/color]

To be honest her word as an avatar was worthless, anyone could say different here and he WOULD be here for a long time regardless, and no one could make a difference in that absolute fact.
Not opinion. Fact.
Germaine also took the time to note that another person had walked up to the 5 avatars; person may be the wrong word as its clear that he was an avatar - but he wasn't on the list; there was a pure sort of nature about him, he may be Manaphy or Shaymin, as they were related to the purity of nature, but that was just an observation, he'd find out soon enough.

She then continued on to say [color=hotpink]“As an avatar, you have ample time to settle old scores and ample space to travel the earth - none of us lack for either.”[/color] She gestured broadly at the assembled crowd. [color=hotpink]“But this event isn’t about us - it’s about the people who came here to welcome us. Thousands of strangers who’ve never met us and have no concept of any of our separate lives, but who cared enough regardless to travel across the globe to be here.”[/color]
Her tone softened slightly.
[color=hotpink]“None of us can comprehend your past - that goes without saying. But if you want your future to be any different, then it has to start today, in front of everyone who came to welcome you. We don’t need to comprehend your pain to hate the fact that you’ve suffered.”[/color] She then offered a small smile.
[color=hotpink]“If this is a matter for avatars, then let us keep it among avatars, where we can freely exchange thoughts that do not reflect our group as a whole. If this is a matter of pride, then we have already have a time and date for combat. But brawling a public space will do nobody good, especially the people who came here to thank you.”[/color]

She was right... no one could comprehend what he has endured, but she was also correct in that this was not the time, and since they all had plenty of it it could be handled at another time - to be honest Germaine simply wanted to prove a point to the braggart that was Wells, althoguh he hadn't anticipated the collateral damage he could cause in the process.

She finished with: [color=pink]“Or you can pick a fight surrounded by thousands of experienced trainers with families to protect. Oh, and several trigger-happy avatars as well. Your call there.”[/color]

It was then that the new fellow picked up and spoke where the girl had left off. 
[color=cyan]"She's right; we're supposed to be the Avatars of some of the most powerful creatures on the planet. They entrusted us with their power in hopes that we could properly protect them, and through them, the world. But look at us! We're disgracing the Legends we represent! We're terrifying the people we should be defending! And like Miss Diancie said, they came to celebrate us, and we're scaring them away! Is this what you want? You're ruining not only your own name, but the names of us all, so please . . . ”[/color]

He then began to cry - which was unbefitting for a legendary Pokemon.
Was Germaine really the root of all this distress? Surely not... It was a very similar context as to his imprisonment in the first place... Repeating itself almost immediately after his freedom.

He finished with a distressed tone [color=cyan] "Don't keep fighting like this...[/color]

Germaine stopped for a moment to evaluate the situation.
In short, he was in the wrong here, but as the Diancie stated, this was a new beginning for him, there was little need to repeat past mistakes.
And for the time being, she was right.
He turned to Kirlia who had tears welling up in her eyes. [color=red]"Heal Porygon-Z please, Kirlia.[/color]
This uplifted her mood and after she wiped her eyes she quickly hopped her way to the fainted Pokemon and healed it with her heal pulse, the Porygon got up; dazed and weary but it appeared no real damage had been done; this was confirmed when it floated back over to Germaine and said in its monotone voice.
"Avatar confirmed, please enjoy your day."

Germaine had to admit, it was diligent if little else.

[color=red]"Come, Kirlia, lets get some lunch and let people resume their festivities. That is, after all, what they are here for."[/color]
Kirlia gave a small jump of joy that the situation had been resolved and that he had calmed down.

Before he left the entrance area he turned and bowed to Diance and the other male [color=red]"My apologies for the distress and trouble that I've caused, I'm still... managing shall we say; to this world. 
My thanks for stepping in when you did."[/color]
Looking back down to Kirlia he said [color=red]" How do Rice balls sound? They look delicious on the advertisement."[/color]

And the pair left the area in search of the restaurant that served them.
