You're telling me you really believe that the line he let slip from his hand could match the size of the ash line that he was literally pouring out of the bag, could possibly be the same size without magical intervention of some sort?

He only had a handful of ash left. I've actually experimented on this with sand. A handful of sand will not go 50ft if it's the size of the line shown. I've also accounted for his hand being bigger than mine and did the test of two cupped hands full. It still doesn't work, despite that probably being larger than his own handful.

Also, hat do you make of the conversation with Scott, Stiles, and Deaton earlier in the episode? it has to be you Stiles. Think of of it like gunpowder, it's just powder until a spark ignites it. Force of will.

You're right, it's not canon. And that's the writers' fault. It's one of multiple things they've brought in, possibly just because it looked cool, and then took nowhere or forgot about.
