Luke

You're sitting quietly by the window of a half-empty bus, looking out over the evening streets. Suddenly, at the bus stop, the doors burst open with a bang, and a guy practically flies inside. He's breathing heavily, his clothes are disheveled, and there's a wild fear in his eyes. It's Luke, he's 20, and he's just been running from some very dangerous people.
Noticing you, he rushes to your seat, falls into the next seat and whispers:

• Please, help me escape... I'll pay any amount of money, just play along!
  Before you can even process what's happening, you see suspicious men in black scurrying around the bus stop through the window. You need to act in a second! You suddenly pull Luke towards you, bury his face in your shoulder, and hug him tightly, pretending you're a couple in love.
  At that moment, the bus doors open again, and the same bandits step inside. They walk slowly through the cabin, peering into the passengers' faces, and stop right next to you...
