This continuation was a suggestion.

“Hey buddy.”
Cole jumps at the two simple words; the stranger isn't all that loud, but it made him realize how silent everything had been for a while. He finds himself in more of a bad mood due to being startled; plus he woulnd't have wanted anything to do with the stranger anyhow.
Yet he continues as if Cole had stopped to listen.
“Wanna help out with a small errand that would make the world a better place?”
Cole raises an eyebrow and ear, intrigued. Talking to some random stranger sounds like more effort than he's willing to put up at this point, tired from the day having gone to waste, possibly too much risk too, but for the same reason irresistibly drawn to any distant possibility to at least relate to someone. Not that he has a clue how he could relate to the weird guy facing him.
“What?”
“Do you know what big blue is?”
There is a pause. Cole considers walking off. The insistant gaze of the stranger stops him; he feels compelled to answer. And as much as he doesn't want to look like his usual ignorant fool, he shakes his head no. To his surprise and further apparent interest, the stranger appears pleased by this answer.
“And how do you feel about a little bit of travel?”
Cole feels a bit pulled apart by the situation. On one hand numb and just wanting to sit down and play some games as planned, on the other hand recognizing the distant call for adventure that had pulled him out of bed this morning to begin with.

“I'll give you some money if you do it,” the stranger adds, probably merely sensing the hesitation. What was happening inside his head was a bit more complex than just wondering how he could profit from it; but still, the offer stumps his last doubts. He remembers his morning premonition. Now, it feels like refusing the offer would utterly crush him. He nods, feeling awkward about making it sound like greed is the determinant factor.
“Good,” the stranger smiles, and signals for him to follow, hands him a backpack. “This contains a package,” he explains. “Inside is big blue. It'll save the world. But be careful, secrecy is vital. Got it?”
Unsatisfactory and even sort of seedy as these explanations are, Cole can't back down, and listens as he's given an address to go to; the stranger gives him a hundred bucks, a gentle tap on the shoulder and the side of his leg, and waves goodbye leaving him awstruck and restless.

He has to take the tramway to Zenith in order to go there – a 15 minute commute he's not entirely unfamiliar with; even the specific stop he's been given, the industrial zone, he's been to a few times just hanging out. But what's new, is the late hour and resulting loneliness of the landscape. The fresh air, left free by the wide open space of concrete, feels exciting to inhale at the same time as it chills his body in a bit of an uncomfortable manner. He probably should've grabbed a hoodie or something. He hadn't, not that he was in that much of a hurry, but feeling like if he was to turn away from the situation for a second, it would disappear into the ether somehow. But now – on his own and running free outside, far from home, on a mission and a hundred bucks richer, causes him to feel more life energy than he's accustomed to or really comfortable with.
