Yeah, I refer to Mesprit as female and Azelf and Uxie as male, just to make it easier.

Mesprit hated feeling trapped more than anything.
She'd been powerless when those Galactic commanders came for her and her brothers, powerless to stop their leader from taking their crystals to form his red chain, and now she was powerless to stop his ultimate plan. If it weren't for that trainer they'd never have escaped from that lab.
Cyrus had Dialga shackled to the Spear Pillar, forcing him to use his power. As he stood before that trainer, menacing and cold, Mesprit made a decision.
No more! She gestured for her brothers to follow her. They owed their lives to this trainer, whose kindness and compassion had driven her to such a dangerous place just to save them and now Dialga.
With a cry, the trio surrounded the shackled deity of time, and Mesprit flew to the trainer's side. The red chain crumbled away, and Cyrus gasped.
We'll see who's powerless now, Mesprit thought.
