Didn’t Nick put the stick in the tunnel? Maybe it will come show bring those skeletons back to life. Maybe that is why it is dangerous as well as a good thing.

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!

Wait… What? How is Diana that old? I’m so confused

They’ve established–without really stating it outright–that Diana ages very quickly. I mean, if each season takes roughly a year, she was born slightly after the middle of season 3 and yet showed up at the end of season four as a kid who looked to be around three years old. At that rate of aging, looking like maybe a nine or ten-year-old a year later doesn’t seem all that unreasonable.

This is actually a trope used a lot in order to get characters introduced into the plot as babies to an age where they can actively participate in events. It’s called a Plot-Relevant Age-Up.
