The Next morning...
Mulder was eating breakfast and Scully was breast-feeding William.
"So, how are we going to tell everybody the good news?" Mulder asked.
"I'll call my mum, you let the Gunmen know and we'll see about anyone else." Scully explained.
"Alright. I'll start moving my stuff over here, I think it's a bit silly that I didn't move in with you already." Mulder mused. "If it wasn't for the fact I paid for rent a year in advance, I would have moved in with you."
"I know." Scully nodded. They kissed each other before Mulder left. Scully got up and picked up the phone before calling her mum.
"Hello?" Asked Margaret Scully.
"It's Dana." Scully answered.
"Hi Dana, how's William?" Asked Margret Scully.
"He's fine." Scully answered. "Anyway, I'm engaged."
"To Fox?" Margaret sounded shocked.
"No mom…to Assistant Director Skinner…" Scully laughed. "Of course to Fox mom, do you really think I'd marry anyone else?"
Margaret was silent for a moment. "Finally!
While Scully and her mum were discussing the important details, Mulder was visiting the Lone Gunmen.
"So I have some news..." Mulder began.
"You can't be serious?" Byers asked.
"No fucking way!" Langley cried.
Frohike couldn't speak from shock and just pointed at Mulder's finger, with his engagement ring.
Mulder smiled. "Oh I am serious."
They all hugged each other.
"Thank God you finally pulled your head out of your ass!" Byers joked, causing everyone to laugh.
Nobody dared to mention that Mulder had been briefly married to Diana 'the bitch' Fowly in 1990, short enough for it to be annulled. But everybody had forgiven Mulder for it, since he was young and lonely and stupid. By the time they had reunited 8 years later, Mulder became emotional and irrational. The only consultation, was that she was dead, allowing Mulder to move in and get together with Scully. And Diana was never mentioned again.
Afterwards, Mulder went to his apartment and gathered all his stuff (which was much smaller than it used to be, since he gave his porn stash to the Gunmen when he and Scully got together), before leaving for the last time and moved into to Scully's apartment. Scully made sure William was asleep before going off and visiting Skinner at the office.
"Mulder, Scully, nice to William looks healthy." Skinner commented.
"Thank you sir," Scully said. "Anyway, me and Mulder are engaged!"
Skinner smiled. "About damn time."
"Anyway." Scully continued. "We've been thinking about the future and we have decided that it would be best if I left the FBI and worked elsewhere."
"Where?"
"We're not sure, but money's not an issue for the time being." Mulder explained. "Since my parents were quite rich, and their both dead, I got all their inheritance. I put the money in a safe place if something bad happened to me, which it did. After I was safe, I retrieved the money and now I'm rich, which is why I didn't even try to look for a job after Kersh fired me."
Skinner was shocked. "I never thought you would give up the X-Files."
Mulder shrugged. "Well, ever since I came back, I've realized something: I don't need the X-Files anymore. My personal investment in it is now non-existent since I've solved all the mysteries I want to. Besides, it's in safe hands with Doggett and Reyes."
"Speaking of which..." Skinner indicated to Mulder and Scully to turn around. They did and saw Alvin Kersh being led through the hallway in handcuffs by multiple agents, including Reyes and Doggett.
"The security tapes of the nights of us fighting the super soldiers and Billy Miles were misplaced, but were recovered and will be used in the upcoming trial." Skinner said. "He will pay for everything he's put you through."
Mulder and Scully nodded, with Scully deciding to tell Mulder about the dreams soon.
