With Shortness of Breath (джен)

Shakily, Tim slowly lowered himself on his knees. So maybe the ice wasn’t as sturdy as he originally thought. He would be fine.

Before Tim could even register the loud cracking of the ice, it splintered and he fell through with a surprised gasp before everything became white. He heard Jason shout his name as thousands of icy needles of freezing water stung every part of his body. 
 
He was fully submerged and the world went from frigid blue sky to half-frozen green waters.
