Last Breath

The first in the whole monochrome scene thing, which is also why it's not given any depth.
When Dash went crazy, and on his spree of killing, his focus was Mack, because Mack had Amanda's heart, and Dash didn't... Subsequently, after about twenty other allies, he finally killed Mack. Amanda found Mack just before he died.. and his last breath faded away in her arms... as depicted here.

Dash still lives, wishing for her still.
