Donnie doesn't know you personally; that didn't stop him from knowing you at a certain level. Things about you, how you fight, what drives your ability to survive in this hellish Kraang alien apocalypse. It's not that you're particularly interesting, he's just...oddly invested.

Which is the main reason why when one Kraang launches at you from behind, Donnie easily uses his ninpō gun to blast the alien to bits, pink blood splattering every whichway.

He stared at you blankly, glancing up and down at you subtly before shooting another bastard alien.
