"Daddy, why isn't Papa home yet?" Arthur Kirkland looked down at his youngest son. The blond boy was already in his pajamas and was clutching his stuffed polar bear doll worriedly. Arthur smiled reassuringly at the little boy.

"I'm not sure when your papa will be home. He's with Uncle Gilbert and Uncle Antonio tonight. H e may not come home in time to tuck you in tonight but I'm sure that he'll make you some nice pancakes for breakfast in the morning if you're a good little boy and go to bed on time."

Matthew's lip quivered. He want his papa to tuck him in. He loved Arthur, but Mathew liked his papa's stories better than the ones that the Englishman was fond of telling.

"MATTIE! Mattiemattiemattiemattie!" Matthew's older brother, Alfred ran in wearing a mask and a spangled blue cape. " Come play superheroes with me Mattie! You can be my sidekick, Maple Boy! And I'm the HERO, Justice Man!" Alfred ran around Matthew and Arthur, yelling about the amazing adventures of Justice Man and Maple Boy. Arthur sighed and smiled wearily.

"Alright now Alfred calm down. Bedtime is in fifteen minutes, so please don't make a mess."

"OK! C'mon Mattie! I wanna play superheroes and ya got be my sidekick, ya gotta!" Alfred begged as his father winced at his eldest son's battering of the English language. But he smiled again a few minutes later when he heard his sons giggling. He sighed when he noticed the clock, hating to ruin his boys fun.

It was sometime around two am when Francis finally stumbled home. Arthur had stayed up and was just considering going to bed without his husband when he heard the door open and slam shut. Arthur frowned. Even drunk Francis usually was very quiet when he knew the boys would be in bed. And now he was making quite a racket.

He stepped out into the hall. "Francis, what are you doing? You'll wake th- "

"HOW COULD YOU? Angleterre, how could you?" Francis screamed. He was even more drunk than he usually got when with Gilbert and Antonio, but that wasn't what worried Arthur. No, what worried Arthur was the fact that Francis was sobbing.

"Francis, please. The boys are asleep. Please just calm down and explain what I did that's so unbelievable." Arthur frowned, trying to remember what it was that he had done.

"Is it that forgettable? No wonder I haven't heard about it before. And with one of my best friends! Mon meilleur ami! Je te deteste!" Francis burst out in a fresh wave of tears.

"What? Francis, you know I have absolutely no idea what you're talking about. Come along to bed, it'll be fine in the morning-"

"Non il ne sera pas bein! Tu m'as trahie! Avec mon meilleur ami!" Francis had completely lost it now and was babbling in rapid French. Arthur scrambled to understand what exactly Francis had said.

"Francis, please." Arthur went pale. No. Nononononononono. Not that. It couldn't be… He couldn't have found out about…

"Francis let me explain. Y-you don't understand. I was angry and drunk and I wasn't thinking."

"That's always your excuse! You could have stopped though! BUT YOU DIDN'T!"

"Francis please keep your voice down! Think of Alfred and Matthew! Do you want them to hear this?"

"I am thinking about them." Hissed the Frenchman. "Especially about Alfred. It was about nine monthes before he was born when you cheated on me, non? So I have to wonder, is Alfred my son or is he Antonio's?"

"Fran-"

"ANSWER ME!"

Arthur flinched. He looked into Francis's eyes, begging him to just forget this and come to bed. Francis looked away. "Francis please. Please, I'm so sorry. I-I can't – I don't know."

Francis turned and walked out of the room. Arthur followed him to the door of the boys bedroom. "What are you doing? The boys don't need to know about this. Francis!"

"Mathieu est mon fils, n'est pas?"

"Erm- yes. I still don't understand."

"I will not stay with you, you cheating bastard. So I will take mon fils et I will leave." Saying this, Francis swung open the door and entered the room. Arthur stood frozen in the doorway as Francis silently padded to Matthew's bed, gently lifting the boy out of bed.

"Mmm, Papa?" Matthew mumbled sleepily. Arthur unfroze and leapt forward.

"Francis! I can't let you do this! Matthew is not just your son! You can't take him away from me!" Arthur's cries had awoken Alfred. "Daddy? What's goin' on? When did Papa get back?" Alfred asked.

"You still have Alfred, non? But Mathieu is my son, that I know for sure. So now we bid you adieu." Francis snarled.

"Huh? Papa where are we going? Why isn't Daddy coming too?" Matthew asked, confused as to why his parents were fighting and why he and his papa were going on a trip so late at night.

"You're not going anywhere Matthew! Francis stop this instant! Put Matthew back in bed, and let's talk about this."

"Non." Was the simple reply.

"Daddy? Is Mattie leaving? Daddy! Don't let Mattie leave!" Alfred was panicking, afraid that his little brother and best friend was going to leave him and never come back. He jumped out of bed and clung to Francis's leg, attempting to keep the man from walking out with his little brother. Francis tensed up at Alfred's touch. He looked down at the determined little boy, torn between anger and compassion. He did love the little boy even though he was furious at his husband and was unsure whether the boy was even his. But his anger won out and he shook Alfred off.

"Francis please! I'm begging you, don't do this!" Arthur gasped, tears flowing down his face. He and Alfred followed Francis and Matthew to the front hall, begging and fighting the Frenchman's resolve to no avail. Francis walked to the door and paused. "Au revoir" he said simply, and walked out the door.

Matthew struggled in his papa's grip, not wanting to leave his daddy and big brother in such obvious distress. In his struggle, he didn't even notice that he had lost his polar bear.

"DADDY!" He screamed, reaching back over Francis's shoulder. Arthur fell to his knees sobbing, knowing that there was nothing he could do. Alfred ran past Arthur only to be snatched back by the Englishman. "There's nothing we can do." He whispered "Nothing."

O.O
I left off on such a sad note! Yeah, so this was actually the first fanfic I even wrote, but I never really got around to posting it. I got the idea while watching a History channel special about the first Europeans in America. It mentioned that the English and Spanish were the first to settle and fight over America, the French coming in a bit later. So the first thing that popped into my head was "OMG! Arthur cheated on Francis with Antonio!"
Oh and I changed up the boys ages a bit. So instead of them being twins Alfred's about 6 and Mattie's about 4 or 5.
