Magnus was about to reply when something gorgeous came into the room. She was magnificent, her radiating light literally had him rooted to the spot as she deepened his shadows with her contrast. His eyes were locked on her as he reached into his silk pants and pulled out a key to set near Jax's plate. 

"Go sleep in my room, end of the hall. I'll make you one in the morning. Welcome to the family."

No snide, no sarcasam, he was clearly no longer interested in the bugboy and would probably regret letting someone into his room later. But it could wait, who was this one? Obviously one of the new arrivals but he couldn't place her, he would remember someone who glowed like a sun and moved on the breeze. He watched on in stunned silence as she moved around like no one mattered while she wet herself down, evaporated water harmlessly, then put her head to the glass to drift off like she had always been here at the mansion.

He never noticed if jax left, he didn't recognize the other who came through or the cereal sitting out now. He didn't know how long he had been perched on the edge of the kitchen counter or even when he had set himself like a gargoyle watching over her shifting colors, lost in the trance of her vibrancy. Here she was, radiating light with no seeming way to diffuse or dismiss. Did she not care? Could she not turn it off... like him?

Her change was so subtle you never really noticed until you had to look again to see you couldn't see it. Like the full moon giving away its light to the overbearing sun or watching a rose open its petals. It wasn't until she moved that he realized she was completely different. For one thing, she wasn't floating, she was falling!
*BAMF*
He was already falling to catch her when he closed the distance on instinct, years of practice made his own motions rote and simple as he twisted in the negative space of his paternal dimension to catch her in a cloud of brimstone. He coiled his tail at the small of his back to protect his fused discs as he cradled her head into his stomach, he curled his shoulders up to prevent his own head from hitting the floor as right arm and leg stretched out under her to take the impact with left limbs poised to take the shock of weighted impact.
"Oof!"
