'blah' means thoughts
This is an excerpt from book five (Chapter 28) but it could also be from the past. I changed it around a bit to make it an SS/LE ficlet.
"LEAVE HIM ALONE!" Lily shouted. She had her own wand out now. James and Sirius eyed it warily.
"Ah, Evans, don't make me hex you," said James earnestly.
"Take the curse off of him, then!"
James sighed deeply, then turned to Snape and muttered the countercurse. "There you go," he said as Snape struggled to his feet again, "you're lucky Evans was here, Snivellus."
"Lily! Don't involve yourself. I don't want you to get hurt!"
"Don't talk to her!" James hung Severus upside down again.
"It's all right, Severus." She turned to James and Sirius. "LEAVE HIM ALONE!"
"Ah, Evans. You wouldn't hurt us."
"Don't tempt me, Potter. I can do more than you would ever HOPE to achieve."
"Did your boyfriend teach you his Dark Arts material?" Sirius sneered.
"Severus wouldn't teach me any Dark Arts whether he knew any or not! Now, for the last time, LEAVE HIM ALONE! PUT HIM DOWN!"
Sirius looked over his shoulder and then whispered to James. "Mate, better do as she says. McGonagall's coming!"
"We'll continue this little chat later, Snivellus." James flicked his wand, causing Severus to fall face first on the ground. The Marauders (minus Remus) disappeared from view. Lily walked over to Severus and helped him up.
"Are you all right, Severus?"
"I'll live, Lily."
"I'm glad." Lily pulled the young Slytherin into an embrace.
"Mr. Snape, Ms. Evans. Are you two all right?" Professor Minerva McGonagall asked.
They Gryffindor and Slytherin separated and faced the Transfiguration Professor. "Yes, we're all right, Professor," Lily said,
"But you will be needing to spend quality time with James and Sirius," Remus spoke up, walking up to them, clutching his Transfiguration book to his chest.
"Why is that, Mr. Lupin?"
"Because they were hexing Severus again."
"Again? Mr. Snape, how often do Mr. Potter and Mr. Black hex you?"
"They hex me whenever they feel like it," Severus said softly. Lily put an arm around his waist.
McGonagall raised an eyebrow. 'A Gryffindor and a Slytherin? A muggle-born and a pureblood? This is a good step in beating house rivalry. I hope they stay together.'
