Demons don’t have to stand on top of a trap (if it’s on the ceiling for example), so if someone would hold a trap on top of a demon and move it around, would the demon have to follow it?
If yes, would you be able to drag them around on the ground with the trap?
Ever see an episode of Angel where he leans against the magical door barrier like its a physical wall, until he’s invited in? I imagine it’s like that. Moving the trap would literally drag the demon. So, yes.
