Cue a very upset sprite with two extra giant giants. Seriously guys!
There isn’t currently a story like this, but once again we’ve mused on it. There would be a lot of sprite curses, Dean glares, and Sam probably offers Bowman some beer and discovers what a lightweight the guy is.
Seriously, Dean, does this really look like a threat? *Shows Dean the sprite that can’t even fly straight anymore.*
It would be one of the most interesting ways to “trap” the sprite. Can’t stay in the air, can’t fly away. Even if he manages a good hop, his wings will be too wobbly to get him far and they can just bring him right back to the table.
Cue Bowman accusing Sam of trying to poison him and assuring them both that as soon as it wears off, he will bop them and then fly himself home. Because that’ll surely scare them off, Bowman.
