Obsessed with how Crowley's plans for getting Nina and Maggie to fall in love develop over time. He's clearly thinking about this and expanding on it between scenes.
A sudden rainstorm forces them together beneath a canopy? They look into each other's eyes… And realise they were made for each other?
Get humans wet and staring into each other's eyes, vavoom, sorted. I saw it in a Richard Curtis film.
Humans, riiight. Still it's a nice simple plan: rain, humans, looking into each others eyes. Crucially, at this stage there is NO KISSING.
Not resting on his laurels, Crowley takes time out of his busy angel-orbiting schedule to check Nina's thoughts on rainstorms etc:
Naturally, he's encouraged by Nina's insistence that she and Maggie aren't even friends - clearly this is an epic romance for the ages here, that's one of the main ways you can tell, right?
BUT ANYWAY. Onwards to the following morning, and what's this?
Well, we just need to get Nina to do the love thing with Maggie. One fabulous kiss and we're good. I have a plan.
One fabulous kiss, OK yes, this is wholly new. There was no kiss in the original plan. The kiss is an addition. Crowley's been working on the plan. Expanding it. When did all this happen? How did Crowley come to the conclusion that a kiss was essential?
Did a Soho cinema have a surprise Richard Curtis marathon that Crowley spent the night watching as "research"? Did inspiration strike on his fiftieth Buzzfeed "design a bouquet and we'll tell you your soulmate's initial" Quiz? Or sitting in the park, pulling petals of a daisy while muttering he loves me, he loves me not...
We may never know. But despite his two-for-two complete failure record in engineering romantic moments, I hope Crowley never stops. Keep plotting, you ridiculous lovesick demon. One of his plans is bound to work eventually.
