The Kingsman have nine lives, explains Harry, sitting between James and Charlie, his voice low and soothing in the wake of all Eggsy's yelling. Charlie doesn't look any different, and he'd never met James, but Harry looks like someone rewound his life to his twenties.
What Eggsy comes to understand, after long talks of blood rituals and the literally reviving powers of scotch, is that most of the Kingsman are the founding members who lost their heirs in World War One.
Which explains - or at least he'd like to pretend it explains - how bloody weird they all are.
But it's Charlie who comes at him first, so maybe there's just something in the water.
