Douglas takes Martin out to a friendly dinner during a layover, just because he doesn't feel like eating alone. When he comes back to their table after a visit to the toilet, he finds Martin not alone. There's a man at their table, Martin's age, who is apparently in the middle of an abusive rant aimed at Martin - that he'll never find someone, that his date must have escaped under pretense of going to the toilet, that he's as pathetic as he's always been etc.

Feeling charitable, Douglas steps in and introduces himself as Martin's boyfriend/fiance/husband, pleased to meet you, now please leave the love of my life alone and go away before I hurt you.

The man introduces himself as Simon Crieff and invites them both to Martin's mother's birthday dinner, which, conveniently, happens to be the next day, while they're still in town.
