That's exactly what I'm talking about! I'm imagining she copied the pocket dimension part from somewhere without fully understanding it. This is why magic used to be viewed as unpredictable, because people would(and still do) cast spells without knowing what they were [i]really[/i] doing. And then it's usually fine, until it isn't. 

At some point, this will cause a problem. I don't know what, why, or how exactly, but it will.
