This was inspired by a chapter posted by JohnDoe1234. The premise is:

One night after too much partying with Neville, Draco and Blaise in Las Vegas, Harry wakes up in his hotel room next to a woman he doesn't recognize and realizes that she has Lady Potter's ring on her finger. Harry races to tell his friends and while he is explaining the situation Pansy Parkinson, now Potter, walks into the room wearing Lady Potter's ring. This story is AU. James and Lily are alive. The only set pairings are [Harry P, Pansy P] and [Draco M, Hermione G] While this is the first time I've posted a story online this is not the first story I've written.

Fair warning: Updates are most likely to be slow going. I am working on a much bigger project and have little free time as it is. If you like the story feel free to follow/favorite it. I welcome all responses/critiques and will read all comments. I do not have a beta so inform me of any mistakes and I will rectify them asap.

Chapter 1: The Hangover

"Merlin, my fucking head hurts." Harry complained as he rubbed his temple. "Draco pass me one of the hangover potions, will ya?" Draco tossed a small vial from his armchair in their suite at the Bellagio and Harry wolfed it down. Counting to ten, he waited for the serum to take effect. Finally, when the pain had subsided he looked to his friend. "Draco, wake up Blaise. We need to find Neville. I don't care what you have to do to find him, but we need him to ditch the slag he's with and get over here so we can retrace our steps. There is a lot I don't remember about last night."

"Keep your shirt on," Draco snapped. "Why don't you and your lovely bride grab some breakfast downstairs and by the time you get back I will have recovered our timid friend." Draco said to them with a wink.

Without another word, Pansy grabbed Harry's hand and dragged him from the room to the elevators. As they made their way to the lobby restaurant Harry finally found his manners.

"How are you holding up, Pansy? This must have come as a shock to you too." Pansy gave him a sideways glance before saying, "What happens in Vegas, right? I didn't expect this to happen of course, but after what I was doing last night I am not totally surprised that something like this happened."

"What were you doing? In fact, why are you even in Las Vegas? What are the odds that we would both be halfway across the world at the same time in the same place? That is a huge fucking coincidence."

"There are no coincidences, Harry." Pansy said vaguely. "It is Easter break at the Ministry and we both work at the Ministry. There are only a handful of Wizarding getaways that can truly be appreciated in less than a week, and Las Vegas is one of them. Hell, any more than four days here would be enough to get a Wizard placed in a Muggle asylum."

"My Godfather spent a month here with my Uncle Remus after they graduated." Harry told her, "They only left town for the full moon. He would have gotten a flat here if it weren't for my dad dragging them both back to their respective careers. I hear the duel that followed was a sight to behold."

"Well, any normal wizard would go mad after a week. Your Godfather is not a normal wizard. The Blacks are known for their eccentricities, and perhaps, since most of them are born mad, this city normalizes them." Pansy sneered back as she finished. Harry rolled his eyes at her, but kept his tongue as their waiter had arrived to take their order. After they had both ordered a modest breakfast and been left alone, an awkward silence crept upon them. They had been dragged back to reality, and the enormity of what must have occurred mere hours ago was beginning to crawl back on their shoulders.

"To answer your question, Harry, I was barhopping with Tracy Davis last night. We were at our sixth club when a pair of sleazy looking Muggles came up to us and tried to get us to come home with them. Tracy was a few drinks further in than I was and she tried to talk me into it. When I refused, she took off with them alone. I didn't see her because I had gone to get another drink. When I came back she was gone. I think one of the guys was still near and while I was looking around he slipped something in my drink because shortly after that I started feeling sick and euphoric. I went to the restroom and tried to apparate back to our room, but I must have overshot it because I wound up in the mezzanine at the Bellagio. The last thing I remember is that I saw you turn the corner downstairs with Neville and Draco and I tried to follow you. After you took off this morning I got ahold of Tracy at our room. She apparently ditched the guys shortly after I disapparated and went looking for me at the room. When she couldn't find me, she started to worry but waited, hoping I'd show up." When the food arrived, they ate in silence. Harry finished his meal first and then began mustering up the words he'd been holding back from saying all morning.

"I can't believe we're married. My parents are going to kill me. My mother has had that ring since the day she and my father married. It was locked in Gringotts for two years because my grandparents were killed by Death Eaters. They unleashed Fiendfyre on Potter Manor and set up wards to keep my grandparents from leaving. Dad was the last of his line, so there was no Lady Potter until the day they wed, and now it's on your finger. No offense to you but things could scarcely be worse for me right now."

"Let's get back to the room." Pansy said. "We need to retrace our steps before your parents get here. It's nearly 3PM in London. They have to know that you're married by now. The next international portkey won't leave until morning so we have about sixteen hours before they arrive if they're coming. Are they the type to send an owl or Patronus beforehand or would they just show up without warning you?"

Impressed with her sharp mind this early in a crisis, Harry recalled that Pansy had a job in the Portkey office at the Ministry. "For something this big they wouldn't owl ahead. More than likely they are prepping to Portkey over in the morning like you said. We need to get some information ASAFP." Seeing Pansy's confused expression, he explained, "As soon as fucking possible, it's a Muggle saying. It's supposed to save time and yet look at how much time I wasted explaining this to you."

They made their way back upstairs, and when they finally made it back to the room they walked in on a thoroughly disgruntled Neville, looking disheveled and just out of bed. "Finally, Harry. What the hell is going on that you had to send Draco to drag me out of bed when I had fucking Gwenog Jones disrobed in bed!"

Draco sneered, "What Neville means to say is that I dragged him out of bed while he was fucking a disrobed Gwenog Jones." Harry looked mortified. "Congrats Neville. Draco, you truly are a fucking wanker for doing that but I love you all the more for it." He paused before continuing. "Neville, we are in deep fucking shit, or that is to say, I am in deep fucking shit. I blacked out really early on last night, and when I woke up I was in bed with Pansy here, and she has Lady Potter's ring on her finger!"

Neville choked on the hotel-room coffee he had just begun to drink. "You what? Your parents are going to kill you. Have you heard from them?"

Pansy took the question. "They haven't responded. We think they are going to catch the next portkey here and confront him in person. That gives us less than sixteen hours to figure out what the hell happened, and what to do next."

"Fuck," replied Neville. "Well let's get started then. Everyone turn out your pockets. Harry, tell us everything you remember. We need to know where to start."
