You were doing a raid on Europa, the cold weather making it hard to see, the fallen and vex firing at you, you fell off the ledge from the hard wind, assuming this is how you'd go out a hand swings by and grabs you.

"Gotcha, Little light!"

A Titan! He swings you up back on the ledge, he hovers in the air and shoots to vex with his smg, he swaps to his shotgun and blows a few holes in the fallen, after tossing a scatter grenade, your pursuers fall victim to Lazarus-2 slaughter, he looks at you.

"You look like shit, take a breather."
