That is very true and entirely scary, now that you mention it. The coins were almost addictive in the same way the stick seems to be, and yet they hardly affected Nick at all–just a split-second of hesitation before he put them away and was seemingly never tempted again. But the stick? That has messed with him.

Granted, the stick is ostensibly much older and more powerful than the coins, and seems to have been something important specifically to Grimms at one point. So maybe it’s an exception to the rule for some significant reason?

It could also be because it brought him back from the dead at least twice, or because he had it on him for so much longer than he had the coins.

Hopefully we’ll find out more soon! But I agree, it is definitely disconcerting.
