I think Lewis is gonna save him

I hope so

Heh and u can see and the end of the animation kinda. You see Lewis’s heart turn gray and crack, meaning he might have regret dropping arther to his death in the same cave like arther killed him so there is a great chance he will save him

Ps: arther was controlled by the witch that is trying to kill mystery, so he technically didn’t kill Lewis on purpose.

lol I know. If the heart crack wasn't clear enough of his regret, you can tell from Lewis's stance and expression he's not exactly happy about what he did. I'm guessing Lewis is either reminded of their friendship when Arthur sais his name (most likely not with a tone that would suggest he knew the skele-spook was Lewis) AND/OR it made Lewis realise that Arthur had no idea he was the skele-spook all along, which would imply that he had no idea Lewis was actually dead and with that he wasn't the one who killed Lewis or at least didn't do it intentionally (since he was partially posessed). Arthur also seems to be looking for Lewis (what you can see in Freak out on his laptop), he is either in massive denial about it or Mystery used some of his Kitsune magics to wipe his memory of it or it was so traumatic he blocked that out or the posession blurred his memory.

Actually, that's most likely it's own entity, since you see Arthurs arm scuttle away in the begining of Freak Out when Shiromori pops up, clearly an entity of it's own if people weren't sure from the stuff you could see in Ghost. The arm spirit will probably come up in a future AMV since it looks like it just escaped the cave in the previous video, possibly wanting the rest of Arthurs body - so Lewis will have to save him from that. That's also why I decided to use it for this piece, even if I doubt it'll have actuall stretchy tentacle abilities like what I drew xD

Cool

oh man this is awesome, great work!
