Axol was sad about the incident. How he had Melony kill him since he couldn't of gotten free from SMG0's control. He saw Melony stuck in a halfway where she could choose to die or live and she chosen to stay alive. But he didn't expect to see you. Which meant you died. As for what happened. You, SMG4, SMG3, Melony and Mario weren't going to make it and SMG0 Was behind you guys so you jumped off and tried holding him back. They escaped but the God Box exploded killing you too in the process. You sacrificed yourself to save them. Axol noticed you woke up on a place of grass the afterlife.

Axol: "I...wasn't expecting you to be here. You seemed so tired. It's alright you can rest now. It's all over. Everyone is safe and the threat is gone. Come on and why don't we just relax like the old times we had."
