"Hey Honey-Bundles!" Finland called as he walked across the kitchen to the front door "I'm going out to stand uselessly in the middle of a grassy field with my sleigh and reindeer and stuff. I'll see ya when I...Sweden?"
Finland stopped in his tracks when he saw Sweden lying face-down on the living room couch, motionless except for the occasional twitch of his hand.
"Sweden?" he walked into the living room and knelt down by his husband's side. "Are ya alright?"
"Nh..." Sweden mumbled as he half-opened his eyes "N't feeling...m' best..."
It was then that Finland noticed several empty peppermint wrappers on the nearby coffee-table. His stomach lurched as he started to piece the situation together.
Oh no, I forgot to label...
"Um, Sweden...I uh, think ya may have accidentally taken some of my anxiety attack medicine..."
"Nh?"
"Yah, um, ya see I candy-coated the pills so they would taste like peppermint sticks but then I forgot to, heh heh, label them. I'm sorry Sweden! I'm such a silly space-case."
"Hmgh," the tiniest of smiles tugged at Sweden's lips as he closed his eyes "Cute..."
"Sweden! No Sweden-oh dear, he's going to be out for a while. The amount he took he'll be so plastered that he could probably sleep through an alien invasion," Finland sighed and smacked himself on the head "Stupid, stupid me! No, calm down Finny...maybe this is a good thing, yah? I mean he works really hard and stuff so maybe he could use the rest. It's not like anything bad or dangerous will happen while he's out, right?"
Finland lifted his husband off the couch and carried him back into their bedroom. A minute later he had Sweden all tucked in cozily under the covers and was about to turn to leave when his husband's hand caught hold of his wrist.
"Eh?" Finland turned back towards him. Sweden's eyes were still closed, but he seemed to have regained partial consciousness for a moment.
"Love ya...m' wife... Don't ev'r change...Yer..." Sweden's voiced trailed off. Then his eyes flickered open for a second. "Nh...yer cute." Sweden's eyes closed again and he fell silent.
Finland smiled and reached over to stroke the side of his husband's face. "I love ya too Sweden. I'm so lucky to have a husband who is still nice to me even when I do weird stuff, which is about most of the time." He leaned down and kissed Sweden softly on the forehead before gently prying his husband's hand from his wrist and walking out of the room.
Thus explaining Sweden's absence during the Pictonian invasion. If he'd been awake he probably would've gone down trying to protect Finland. But since Sweden was sky-high on sedative-laced peppermints, Finland got transformed while obliviously standing all alone in a grassy field thinking about how he couldn't wait for Christmas to come.
"Ho ho ho!"
