Hey there anon – Admin Liz here. Nick did put the stick in the tunnel. It’d be pretty awesome if resurrection was one of it’s powers (it would explain one aspect of why it is both miraculous and dangerous).
We don’t have much information yet on how exactly the stick works – I’m pretty sure it physically touched Monroe’s arm, which led to it being healed. If that’s true, then it would be reasonable to believe that the stick has to physically touch someone to heal and/or resurrect them.
It’s definitely a good theory! We’ll hopefully learn more about the stick soon and get some answers!
