"Right. Not enough space to do that." Cedric rattles his brain for ideas. There's probably no one around to help them, so sending up sparks should be a last resort. If at all possible, he should get them out of the grave himself.

The clear air helps him think. Logically, they have to do several things: break the coffin, break through the dirt, and reach the surface. It'd be nice if a single spell did all of that, but he might have to combine some in quick succession.

"If I break the coffin now, the dirt will crush us. We're not in the right direction for an ascension spell. And that means..."

An idea comes. He whispers a spell, breaking the coffin below them and pushing them---downward. Pointing the wand carefully to guide the magic. Cedric forces the dirt to tilt their bodies properly, leaving them standing upright underground with the coffin's still-intact top protecting them.

He takes a deep breath. He does have a plan, but it's risky. "Hold onto me as tightly as you can. We've only got one shot at this."
