The Switch

In the Gryffindor common room one night the Marauders sat close to each other by the fire, still puzzled as to what happened that morning. Peter's hair returned to its normal state, James stopped talking gibberish, and Sirius no longer felt dazed, but Remus forgot what had happened in the Great Hall.

"You really don't remember," James asked Moony.

"No, what happened?"

"We were a laughing stock," replied Sirius. "Someone gave us potions that made us act stupid, and I think it was Lily."

"Lily?"

"Yes James, Lily. I saw her walking with Snape this morning, and I remember them laughing at us."

"What's up with them two? They've been together a lot lately." At that moment she waltzed into the room and sat in a chair a few inches away from them. Lily's red hair covered face and she twirled her fingers through it.

"Where have you been," queried Remus.

"I was at the library, studying."

"With who fray tell?"

"I was by myself Moony."

"Yeah, right," barked Sirius. "What are you really up to? What are you and Snivelly doing?"

"Nothing's going on!" Sirius got up, grabbed her arm, and then squeezed it tight. She responded by getting out of the chair.

"Stop it, that hurts," she screamed.

"Yeah, how does it feel to be on the receiving end? Hurts, doesn't it?" Lily let out an urgent cry and James ripped him away from her.

"That's enough Padfoot, don't injure her."

He held her close and then she started to run her fingers through his messy hair. They deeply kissed for a minute and then the Marauders went to their dorm. Lily smiled at the sight of thick, jet black strands of hair in her hand.

A month later the Polyjuice Potion could finally be used. It was Saturday when Lily and Severus decided to do their dastardly deed. They went into an abandoned room and took the cauldron with the brew in there. Lily got out the hairs she pulled from James and Severus yanked out some of his own dirty locks.

"Everything's ready, go get James and bring him here," he told Lily and then she swiftly left.

Not long later Lily finally convinced James to go with her to the room and when they reached the door she jiggled the knob and pretended it was stuck. Severus grabbed a bottle of the potion with James' hair and quickly hid in the closet.

"What's up with the door Lily?"

"It's stuck, just hold on a minute."

"Use magic or something, come on!"

"Look, I got it. Just keep your pants on, or not." They laughed as they entered the dark, and apparently empty, room.

He started to kiss her and then slid a hand on her pink shirt and started to unbutton it, but she grabbed his hand.

"Wait. Wait just a moment." She went to the cauldron and started to scoop some if the liquid into a bottle.

"What are you doing Lily?"

"Close your eyes." He obeyed.

"What are you going to do?"

"I'm going to give you a drink."

"Will it be something with a lot of liquor?"

"Oh, yes." Lily mixed in Severus' hair before she brought the bottle to his lips. He drank the contents and slowly began to gag.

"What was that? I… I feel sick."

James tumbled to the floor and thought he would vomit, but instead his skin tingled. After awhile the sensation ceased and he realized that something was wrong. He saw that his hair was longer, and then felt its oiliness. He caressed his face and found a hooked nose. (James) looked up to Lily.

"What the hell," he uttered. "Do you have a mirror?" She hesitated, but then reached in a pocket on her pants and handed one to him. When he gazed through it he saw Severus, with glasses, staring back at him. (James) abruptly jumped back and dropped the mirror, shattering it. Lily turned her head to her right.

"He drank it, come out Severus." A door opened and (Severus) appeared before them, looking rather handsome. Lily took the glasses off (James) and slid them on the imposter. Then the two ran out of the room and left the shaken boy behind.

"Hey, wait! Where are you two going?" (James) went after them, but when he peered in the corridor they were nowhere to be seen.

(James) wondered out of the castle and searched the green grounds hoping to see them alone so he could attack them. Soon he found his three friends, Lily, and the fake James sitting under a tree, and other students were scattered near them. (Severus) saw (James) coming towards them and grinned.

"Are you bored," (Severus) asked Sirius.

"Yes! I'm bored as hell!"

"Well, here comes Snivelly. Let's hex him or something."

"Yeah, that's a pretty good idea." (Severus) and Padfoot got up to face (James). Remus, Lily, and Wormtail remained sitting on the dirt and watched.

"What are you doing around here Snivelly," questioned Sirius. (Severus) pointed his wand at (James) and recited a spell in his head. (James) didn't reply because suddenly his tongue felt glued to the top of his mouth. He moved his lips but no sound came out. "What's the matter? Cat got your tongue?"

"More like a dog," replied Remus from behind them. The Marauders, except for (James), were laughing, even (Severus), but he had no idea why. He just went along with the inside joke.

"That's enough. Let's hex him James."

With that Padfoot and (Severus) started yelling charms, making (James) do all sorts of things. Sirius made him dance the Tarantella, and then (Severus) used the Trip Jinx to make him fall. The students gathered around them and started to point and laugh at the cursed (James), and (Severus) could see a tear roll down his cheek. He let Sirius take over things for awhile, and Padfoot made (James') legs shack uncontrollably. In that time (Severus) silently hexed the other Marauders. (Severus) pointed his wand to Wormtail and Moony. A minute later Remus noticed that his fingernails were growing fast, and Peter started laughing and rolling on the ground. Sirius was too occupied to detect that he also had been hexed with a curse that made his right eye crust together shut. (Severus) ended the torture by yelling "Expelliarmus", knocking (James) to the ground, legs still wiggling.

"Come on Lily," said (Severus). "Let's drag Snape into the castle." They grabbed (James') arms and carried him back to Hogwarts, dumping him into a boy's lavatory and returning his glasses. The two went back to the room they had the cauldron in and laughed together.

"That was brilliant," said Lily. "I didn't know you had it in you to get revenge. James will be so furious with us."

"He won't remember it though. I slipped another potion in there to make him think that it was all a dream, after he turns back into James."

"When will that be?"

"It won't be long." Severus put an arm around her shoulders. "Are you really in love with James?" She stared into (Severus') hazel eyes.

"I don't know. Why don't I kiss him to find out?" Lily wrapped her arms around (Severus') neck and reached up to lock lips with him. (Severus) placed his arms around her waist, pulling her closer to him, and deepening the kiss. She accepted his tongue and moaned as they explored each other's mouths. When they pulled apart she laid her head on his shoulder. "I think I like the way this James kisses." They continued to hold one another for awhile, and then the next time Lily looked at Severus she saw his true features. She gazed lovingly into his black eyes. "I have another idea to make the Marauders look foolish."

"Really, what's your idea?"

"First off… this." Lily put a hand behind his head and pulled him to her for another kiss. They did it more passionately that time, and Severus began to run a hand through her red hair, the other still gripping her hip. That kiss took longer than the first and they had to catch their breaths afterwards. Their foreheads were touching and he smiled down at her. 'Oh Merlin, how I love it when he smiles,' she thought.

"I love your idea so far."……
