James had changed, realized Lily, and she was feeling things towards him; odd little emotions that crept up whenever he spoke to her, touched her, or even looked at her... And Lily found herself liking this new James- smart, charismatic, kind, and oh-so-adorable... And yet, as if fate had deemed them worthy, she had made them both Head Boy and Girl of Hogwarts. 7th year Marauders.

ONE SHOT Based off of a headcanon I read somewhere on Tumblr. 6th-year Marauders cast their Patronuses in DADA class! But when James realizes what Lily's Patronus is, he gets cold feet and decides to talk to his Professor about it.
