Adalind is a quick learner. I don't doubt her ability to do something untested with little to no experience and actually get results.
The final battle is honestly badly written. I can attempt to make sense of everything that happened since Eve first saw the skull-faced man after being healed by the stick but it's just me grasping.
Everything right up to Nick and Eve fighting in the other world was playing on the characters' psyche, always keeping them on the back foot and fearful. By the time Z crossed over and the bodies started piling, he worn out the last of Nick's confidence and was almost successful in manipulating Nick to give him the stick as opposed to fighting him for it. They told us he couldn't take the stick from Nick but with little reason as to why, is it possibly because Z purposefully avoided in engaging Nick in an all out battle. In the other world, he seemed to be all powerful, maybe he wasn't so tough this side of the mirror.
Nick would have lost had his mother and aunt never showed up and talked him into believing that he (Grimm blood) could in fact beat Z with nothing more than the power of belief. It's a stark contrast to every fight that came before it. From the moment Nick walks up to the cabin to confront Z, his whole demeanor is changed. He's a whole lot more confident than he was in the mirror world, at the station and earlier outside the cabin when everyone he ever cared for died in front of him. Simply put, he believed he could do it (with the help of other Grimm(s)) and he did.
Unfortunately this doesn't explain Diana seeing Nick's relatives. Therein lies the problem. Whatever we come up with to explain The Z plot from its inception, something rises to contradict it. Look at how they handled Eve and Diana and their parts in the story. We were lead to believe they were important only for the writers to crap all over several episodes worth of dialogue and plotting by returning to Nick and his relationship with the stick.
