They took him to the healers.

Or, more specifically, Blue took him to the healers while Mumbo stayed behind in the lab.

He didn't want to be there if they had to break the bad news.
He didn't want to be there to never see Grian wake up again.

He'd rather live in a delusion- only for a bit- and imagine that Grian was alive. He's rather imagine that the prankster was just out of sight, plotting something mischievous and giggling to himself.

Turning his attention to the table, Mumbo sat on the stool, taking in the notes before him through a numb and grey haze. He was reading it, but the words didn't stick, slipping away as soon as his eyes moved onto the next word.

Distantly, he knew that Grian was onto something with the crystals and Mumbo picked up the one on the counter, studying it for something. He wasn't sure what.
It glowed faintly, pulsing with energy like it had a heartbeat. Faint runes swirled around inside.
Mumbo didn't have the energy to translate them.

He set the crystal down gently and turned to the one on the floor, still sparking wildly, glowing so so bright.

The one that stole Grian from him.
He hated that little crystal, glittering on the floor like nothing was wrong. Did it know what it took?
The price Grian had paid for it to exist?
He wanted the crystal destroyed.
But he didn't dare break it- what would happen if it exploded? Blue mentioned that a full grown tree sprouted up from an overcharged crystal.
Mumbo could only imagine how much damage this one would do.

Not to mention that Grian made it for a reason. Pointlessly destroying his work would be a fruitless endeavour. He rest his head on the table, brushing the flowers out of the way.
Mumbo sighed and let the crystal be, sitting in its circle of runes because he couldn't figure out how to safely remove it.

It didn't matter anyway.
A faint crackling sound echoed through the room, and Mumbo glanced back at the crystal.

A flower had fallen onto the runes.
A live flower that he was watching die before his eyes.
Which meant the crystal got more energy.

Which tipped it over the edge.

In a blind panic, Mumbo grabbed the notes and the other crystals in a rush and booked it out of the room. He didn't know what the paper said. He honestly didn't care in the moment. All of his energy was focused on getting out of the lab with whatever work Grian left behind.

It was too little, too late.

Another crackling sound was his only warning before the crystal exploded, sending the contents of the room- including Mumbo- flying into the walls. He clutched the paper to his chest, the crystals crammed into a pocket as he went airborne, the walls rushing at him before he hit it headfirst and slumped down on the floor.

The world was spinning and he had a headache. He probably had a concussion.
He was so tired, a little nap wouldn't hurt. Right?

When he woke, Lemur was kneeling in front of him. She looked like a concerned mother, her head tilted as she spoke words he didn't register.

His head hurt. His back hurt.
The lab was a mess.
How long was he out for?

Mumbo tried to sit up, wincing in pain, and was pushed back down.
"-need to relax."

Mumbo stared at her blankly. The words didn't sound right.

"You need to relax, Dust. I just wanna know what happened." She repeated softly.

His head felt like it was full of cotton, heavy and light at the same time, stuffed so full that nothing else could occupy it.
"I... came to visit Red in-in the lab. Here. And I found him on the floor. S-so I called for Blue and he took him to the healer and I stayed behind.
"There was an explosion- from a crystal- and I passed out." Mumbo stammered out, trying to work out how his mouth worked through the muddle in his mind.

Lemur nodded, apparently satisfied with his answer. "You feel okay? Should we take you to the healers as well?"

"What would...would fae healers do for me? I'm not like you guys. Red said so."

"Magic always looks for a host. The explosion released so much that the other crystals couldn't handle it all...so it turned to you." Lemur started as she offered Mumbo a hand to stand up.
Which he accepted and promptly tripped over nothing, unsteady on his own feet.

He felt something...extra on his back and he twisted around to see it.
A set of wings- similar to Grians- sat there, iridescent and elegant.

Maybe he should have been shocked. Or surprised.
But at the moment, he didn't have the energy to properly react, blinking owlishly at them before facing Lemur again.

"To your healers it is, then." He simply shrugged, leaning heavily on her shoulder. If she was shocked at his apparent lack of a reaction, she hid it well, supporting Mumbo on the walk to the healers.
