If I wrote it, he'd be on the train on the way to meet Beyonce where he'd make eye contact with a drunken squaddie. Anyway, the squaddie'd get up and head off towards the bogs but not before giving an almost imperceptible head gesture to our eponymous hero who, against his better judgement, follows the squaddie into the bogs. Anyway, our hero enters the bogs to find the squaddie smearing that pink squirty soap onto the head of his proud purple manhood before unceremoniously gripping our hero's shoulders, turning him round and ramming his face up against the mirror over the sink where he's confronted with the image of the agonised contortions of his own red & panting face and the khaki shillhouette behind him as he's brutally sodomised beyond his wildest imaginings of neither pleasure nor pain.
Later on, as he gets off the train, he's confronted by the horrified shriek of Beyonce who goes "What's that dribbling out of the bottom of your trousers onto your shoes? Is that spunk? Don't you know that's really bad for shoe leather?".
That's how my script'd go.
