Summary
"Heh," Leo let out as a nervous laugh "A-am I in a . . . in a c-coffin?"
"Now bro..."
It was Raph's unsteady, nervous voice that greeted him, trying but failing to speak reassuringly.
"we'll be there in eight minutes, there's no need to panic..." "Raph is right do not panic and conserve your oxygen!" Donnie finished for him, sounding like he was issuing a demand, but also like he was on the verge of one of his meltdowns.
Realization sank heavily into every essence of his being that he really for real was inside a coffin!
A coffin apparently burried six feet under.
His full bladder instantly emptied itself and the sound of a long, shrill shriek of terror - that didn't make it past the cover of the casket he was actively laying in - flooded his ears.

Summary
Leo had been pushing himself for weeks.
The others didn’t seem to notice — or maybe they did, and just didn’t think it was serious. Either way, the burden of leadership had been pressing down on him like a cinder block on his chest. There was always something to do: another patrol, another fight to plan, another round of training Splinter insisted they complete.

Summary
By eight thirty the lair was running on generator power and Donnie’s ears were ringing so loud he couldn’t even hear the baritone of the motor thrumming out in the open sewers. Note vibrating on the handle because no twin had returned home to rip it off with a roll of his brown eyes before depositing the original propane tank nearby. Donnie couldn’t hear Mikey’s voice as he asked about Leo, he couldn’t feel Raph’s hand as they brought him into the lair to warm up his frozen fingers.
Someone else moved Donnie’s mouth and made his vocal cords vibrate into the open air of their home. Someone else stood in the doorway of their father’s room begging their dad to get out of bed because Leo was missing. Someone else felt the world caving in because all the things that were supposed to be unimaginable were happening right now.
As if panic could knock back a respiratory infection Raph and Mikey hooked the TV up with Donnie’s numb help. The weather report was worse than they last knew. That blizzard that was originally projected to hit tomorrow by one in the afternoon would be here at their doorstep much earlier.
