Larla thought of Lukelan, then burst out of Atheran's house, towards the castle.
"Luke! LLUUKKKKEEE!!!!!!"
The door burst open. "Larla, dear, have you finally come to your senses?"
"Oh Luke! I came to my senses a LONG time ago, but, with you being evil and all, I just couldn't stand it!"
"Then let us be married in the morn! And I guess I won't need this love potion."
"What love potion?!?"
"No matter. It has passed."
So L & L were married the next day, leaving Atheran standing still on his doorstep, scratching his head in confused .
And, of course, they lived Happily Ever After.
THE END, if you will.
