Donnie notices the cars then, but by that point there's no guarantee he can avoid them and that SUV is incredibly huge. He's about to squeeze his eyes shut and fall back to cowering but that blur of black and white makes him look up. The human's found him! But the car-!

The turtle ducks down, dropping the phone (thankfully from not so great a height) to throw his arms over his head at the blaring horn. They're both going to get crushed!! And oh, the noise! He hears it, although it takes him a moment to register that the sound is a pretty strange one. There's more sounds of metallic crunching and for a while Donnie's too afraid to look. He finally dares to open his eyes, looking out from behind his shield of purple.

The cars have stopped somehow, like something huge had sat on its hood. The white-haired teenager's still standing where he is, looking almost bored. ...did he do that?

Now people are yelling and it's not making Donnie feel any less scared about things, but he's done with running after seeing what's just happened. He goes into a full wail, tears gushing as he throws his little arms around Accelerator's leg, crying.
