Falling, falling, falling, forever and ever... on and on through a pitiless void into yet more darkness. Once you had broken the crust of the blackness you were falling into a bottomless pit of it. And then once you'd reached the bottom of this pit there was just a little bit more ready to greet you because… bottomless pits…have no bottom. Duh
It would have been overly dramatic to call it endless damnation but it was at least safe to say that things weren't going very well for Thor post Ragnarok.

Things hadn't been going well pre or during either mind but that wasn't the point. In the last 48 hours alone he and Loki had made it through the literal end of literally everything. This endeavour being made up of a number of sub-tasks, including but not limited to:

Escaping a crumbling Asgard, saving all their people and salvaging their relationship, (if only a little. They were still siblings after all.)

He thought he should at least be entitled to some cosmic sympathy.

Thor wasn't even sure how it had happened. Not the whole adventure, that had happened because of his own heroism, might and general awesomeness.

Obviously.

That was the reason anything happened to him.
No, he wasn't sure why he was tumbling through space feeling the chill of time slipping past faster than a bar of soap on a skateboard. He was used to it via the Bifrost, but that had sparkly lights and was more like a galactic slip-n-slide.

Probably the whole thing was Loki having one last joke before he disappeared. A further jab in the eye before he attempted to scramble to power once he reached Midgard. That was if he too was going. Possibly the bastard had escaped unscathed.

It would be just like his brother to slip through the cracks or find a loophole and end up somewhere cushy with fawning women who were willing to feed him grapes and fan him with palm leaves.

Thor was just considering the question of what sort of grapes he would like when it hit him. Something hard, more concrete than an answer.

The ground.

He met the warm, crumbly surface quickly and with a massive thud which, despite his strength and godly status hurt like hell.

Meanwhile, in her mansion Regina felt her ears prick up. The very hairs on the back of her neck stood to attention, and even though her fingers were wrapped around a cup of coffee she felt the rest of her turn cold. Something was going on!

After the air had come rushing back into his lungs, the world came into view. So slowly it was like swimming through a deep pool of pain and blood. Then all at once it was there, too bright and too loud hurting his eyes. The midday sun felt a billion and one degrees. To block out the sun. Thor flung a hand over his face and meanwhile attempted to unglue his eyes after so long squeezing them shut and screaming.

Finally and with great effort he shifted, moving his limbs little by little until he could sit up.

That's when he saw the dark haired woman. Clothed in a sharp suit standing before him she was positioned with her hands behind her. Only odd thing was that she didn't say a word, but before our hero could start a conversation she produced a tiny box.
With a click the small box spat sparks right at him, sending him into spasms and in the space of one prolonged yell he crashed onto his back, cracking his head damn hard on the concrete again.
It was only out of the corner of his consciousness he heard the woman speak.

A shadow loomed over him as she neared. And a voice came from it.

"Who... The Hell... Are you?"
It was a voice like no other he'd ever heard, except coming from the mouth of his estranged sister. Something about that fact made him eager to retort.

"I am Thor of Asgard. God of thunder" he replied from the ground, the back of his head warm with pain.

"Right… And I'm Regina Mills. Mayor." she offered a hand, which he begrudgingly accepted. Other than that though she didn't do anything to help. Almost as if she expected him to be ready to spring to his feet somehow.
"You know ordinarily I'd think you were lying." Regina continued as she watched him struggle "But since this town is crazy, I'll give you the benefit of the doubt."

"It's True!" Thor responded, clenching his fists letting his hands begin to sizzle with electricity. Once he was on his feet it was far easier to conjor his signature powers.

Regina was again unimpressed however. Her mouth stayed fixed in a stern line "Okay, thunder boy… Why are you here?"

Instead of answer, all he could do was stare at the gadget, terrified that it might zap him again but when his dumbfounded expression went on for far too long the woman named the thing. "You'll excuse me for the taser. Precautionary measures are kind of important here. Safety and all that"
"Where is here? Mid-Earth?" he corrected himself last minute, just in case the mortal thought he was crazy. They had a habit of doing that, even now when he (and the rest of the avengers) had saved them.

"Storybrooke, Maine. But you've not answered my question. What are you doing here."
Oh No… What to say now? How to explain what had happened? How to simplify the last 48 hours into something a mortal could comprehend? There was nothing else for it, he was going to have to state the obvious. Looking at the ground, then looking up at the vast blue vault above him he scratched the back of his head and answered

"I uh... I fell... from the sky"

Thor's response landed with a resounding thud. "Duh. I know." Regina said "But it's usually helpful for me, as mayor, to know what a strangers plan is. Especially if they want to kill, maim, poison or abduct anyone"

"I don't know what I'm doing." He said, at least he was being honest "I just fell"

"Mhm... So you didn't plan where you were going to land? You didn't even think about it."

"No!"

"Okay, sure" She was beginning to rummage around in her pocket again. Probably for that infernal taser device.

"Okay Regina." He managed to spit, before she could pull the thing out and electrocute him once more "If you want a quick run through of my last few days, here you go. I-watched-my-father-die, met-my-long-lost-sister, fought-and-then-rescued-my-best-friend-from-a-creepy-slimeball-grandmaster-type-person I was in a spaceship with Korg and my brother... then I fell out of the heavens."

Suddenly, in an alleyway not far away there was a massive crash, pieces of trash flew out of a dumpster just as someone fell in. They cursed as they landed amongst the tins, bottles and other pieces of trash that hadn't escaped, even sending something that looked like a flair into the air.

"Rather like that, as it happens" The blonde hunk said with a smirk

Regina looked at the spike of light which pierced the sky and sighed. "What now?" But she was gone before Thor could warn her about who might be behind the dreaded sky-beam. There was only one person who could have provided it. Probably.
