You and Finn were once friends, though, after a certain tragedy/argument, you had declared becoming his enemy and ended your friendship much to Finn's dismay and disappointment. He hadn't seen you in months, between all that time he was dealing with the stress of an upcoming war between Princess Bubblegum and her uncle Gumbald. He even lost his grass twin Fern, whom he thought was dead but he somehow lived after their battle. He was just stressed all around, he needed a break from all this adulting he had to do with such little time.
Finn was currently bathing in a calming stream, his eyes closed as his long golden silky locks flowed with the water that surrounded his body. His ears focused on the sounds of nature, remaining calm to ease his busy mind. This would be the only time he'd be stress-free for a long while, and he was going to enjoy it while it lasted.
Unfortunately for him, you were nearby and watching him while hidden within the forest. You were working for Gumbald now, having met Fern and the two of you becoming friends from your mutual distaste for Finn. Right now you were just on a solo mission, keeping your eye on the boy and potentially attacking him while he was at his most vulnerable, though the decision was up to you to decide while Finn relaxed in the water below.
