Hey Winchesters! Guess who's got two thumbs and survived the Apocalypse?

...

THIS GUY!

Uh, Sam? Why are you leaving notes in the car now?

Not me, Dean. No idea where it came from.

Ok, ok, stupid move, didn't realise this was manifesting in writing. I'll try again.

"TADA!" It's me, Gabriel! Yes, archangel of the lord, Norse god of night, trickster and lover supreme, we all know who I am. Hold your applause, please, please. I'm back, and I'm here to help you twits out of your current game-ending predicament. Don't ask how and why, no time right now. Just need a quick run-down of current events to check what reality I'm in.

Gabriel? What the hell, man? You have some serious explaining to do. Obama's president, the apocalypse happened, Cas went coo-coo and thinks he's God. What are you going to do?

Call me Doc Brown, Dean, I've got me a time stream to mess in.

I just want to take this opportunity to note that this whole exchange causes me a shit-ton of worry.

Shut up, Sam.

Alright, guys, I'll be quick. In an alternate existence, I got summoned back to life. There's been a lot of messing around with the boundaries of the various existences and universes lately, so I ended up being able to come here. Cas being God is, worryingly, the least of our worries right now. I'm going to see what I can do with the aid of time travel and trickery, but it'll be a bit trial and error.

Gabriel, how are you doing this?

Simple enough manifestation. I'm going to try and keep consciousness in your minds about checking the dashboard here for notes, so even if I mess up, you'll still think this is how I communicate with you.

This is messed up.

Hush, Dean, it's important.

Remember when this used to be my car? That I drove? Instead of something we take it in turns to sit in and see if notes appear from something we assume is Gabriel?

Fair point. I'll prove myself, hang on... open the glove-box.

Guys?

Did it work?

Way to fill my car with gumballs, douchebag. We've spent three hours trying to get rid of the goddamn fire ants that were instantly swarming over the carpet. Ass-hole.

Calm down, I'll do some history revision and it will never have happened. Some people...
