Psycho Mantis wasn't a hero. In fact, he'd been on the opposite side of the 'hero' scale for much of his life. He killed--it was what he did, and he was good at it. However, since dying at the hands of Snake, something had.. changed. It wasn't that he had any more urge than before to run around Los Angeles saving people like Angel Investigations did. No, it wasn't that at all.
The people in the Hyperion, though.. well. They'd been good to him. They'd treated him like a person, had respected his need for space and quiet, and.. they'd become a strange sort of family for him. For a man who'd never had one, it was a decidedly strange epiphany. They meant something to him. It hurt him when one of them was injured.
So when Katara's death hit him, it felt as if his heart had been ripped from his chest. White noise had filled his ears, vision red-tinted and control completely destroyed.
The next thing he'd known, he was moving through the streets, people and buildings a blur as his telekinesis boosted his speed. --Peter was out there, after all, and he was still alive. Mantis wouldn't, wouldn't fail him as well.
When he reached the site of the destroyed building, he landed hastily, bracing his feet and clapping his hands together, dragging them apart as if he was pulling something open--- and the waters split apart, finding and curving under the unconscious man like a living creature. (Painfully, he remembered that he'd learned that trick with water from Katara--her name had been Katara.) Another gesture, this one more gentle, and the water supporting Peter lifted, slithering over the tops of waves and carefully depositing the man in the sand before dissipating.
Mantis dropped to the other's side, skinny fingers reaching out and not caring, for once, about the physical contact involved. He drew the water from Peter's lungs, a palm swiping dark hair back from the pale, scarred face.
Peter, he urged, desperation and anguish lacing his mental voice, please wake up. You have to tell me where she is. I-- She didn't deserve to lie there under the ruins of a building, and Mantis wouldn't know just how hurt Peter was until he spoke.
