I assumed that too. but just saying. It looks like a well orginized garage, doubt a uncovered fuel bottle was just hanging around near the open doors. But I have no idea I am not a physic.
I hear you i never met the dude, and people can say they are nice as pie. Also it states "I decided to get Ratty’s old engine running… " not a big old group of friends and family. Not to mention if I were to set fire to something I own, and wanted trusted alibis, they sure as fuck wouldn’t be standing near it! So that point is irrelevant IMO.
just playing devils advocate for something to do thats all.
