Finn wasn't stupid, he didn't give it full control. But, he gave it just enough to teach Ash a lesson. He stood up and felt the pain in his chest fade away. "Oh want another taste?", Ash questioned confidently. He raised his hand to shoot another blast, but Finn grabbed his hand and tossed him at the wall, putting a crack in it. Marceline came downsairs. "What's going on down h..." She stopped when she saw Ash. She looked over at Finn, and noticed the shade of his eyes, deep red. Jake looked at her with a frantic expression on his face. Ash groaned in pain as blood trickled down the side of his head. Finn was about to strike Ash again, when Jake ran infront of him. "Finn, you need to calm down!" Finn threw Jake to the side, grabbed Ash by the throat, and threw him out of the Tree Fort. He landed with a thud, and Finn approached him again.
Ash shot another blast at Finn, but he caught it and destroyed in his hand. "W-what the fuck are you?!", Ash asked, his voice trembling.
"Your worst nightmare.", Finn replied. Marceline grabbed him by the shoulder,"Finn please try to calm down. He shrugged her off and lunged at Ash. He created an energy sheild, but Finn punched through it and pounded Ash into the ground. Lucky for Ash, wizards were more durable than humans, but that also meant Finn could beat on him longer. Finn picked Ash up off the ground, only to beat him into it several times. Jake pulled Finn off of Ash,"Dude, you're going to lose control!" Finn threw Jake at Marceline, in an effort to get them out of his hair. It knocked them both to the ground, and Finn went back to beating Ash.
Finn took Ash by the throat, in an atempt to strangle him. Ash set his hand ablaze with a spell and hit Finn with it. Finn dropped Ash, the left side of his face, burning intensely. Ash thought he got a good hit in, but he only succeeded in angering Finn more. Ash tried to run ,but Finn was faster. He grabbed Ash by his arm and hurled back at the Tree Fort, causing him to smash through a window. Ash stumbled to his feet, feeling pain all throughout his body. Finn climbed in through the window and tossed Ash downstairs. He was becoming angrier and angrier with every strike made on Ash. He approached Ash, as he lie on the ground. He was about to finish him, when Jake screamed,"Finn, he's had enough!" Finn looked at Jake and Marceline, then back at Ash. He thought Ash hadn't had enough yet. He knew Ash needed a permanent reminder or he would just keep coming back, and hurting them.
Well, time to vote! Do you think Ash is done, or he needs one last taste so he will leave them alone(He won't kill Ash though) Vote now! Either way, Finn will go back to normal afterward.
