Actually.. it might make sense - I'm assuming Wren hasn't done anything wrong. It is Marge's interpretation that he's offended the spirits. In truth, I think the spirit may have just cast a nice lil' leash about his neck to keep him bound to Chall? 

Sound okay? Otherwise, I really CAN go and have him get to tea, leave the tether in Chall's POV, which would be a neat way of approaching things as well.
