#shell injury

Leo protects Donnie to the best of his ability, curling over his brother and trying to protect him from the falling rubble. Donnie tries to protect him right back with mystic shields, but it's not exactly...

Working out.

Rocks keep on breaking through them, or Donnie forms a shield around a rock and that shatters it immediately.

So it's really just Leo's carapace protecting them both from the onslaught.

By the time it stops, Donnie is practically pancaked into the ground, and Leo is pressed on top of him, shell cracked into a billion smitheries. The only thing keeping him conscious is pure worry that something happened to Donnie.

It's not an unfounded fear, either, since Donnie lost consciousness himself and was also battered by the rocks, though more indirectly. It was more like a growing pressure around them, more and more weight pressed into him. And losing consciousness did away with his battle shell, so it's just his softshell being ground into the concrete flooring.

Leo stays awake until Raph and Mikey arrive to dig them out, the Hidden City paramedics on their way. He tells them that Donnie's hurt, and so they devote their attention to digging Donnie out of the rubble while Leo looks on an falls unconscious.

He wakes up in the Hidden City hospital, who knows how much longer, wondering where Donnie is-- And more importantly, if Donnie made it after such a harrowing experience. Even though Leo, himself, is the more hurt one.
