The ProWren will lock in the fade and stay there forever.
The standard approach with most of this style of kite is to get the kite moving towards you then step
under the kite such that you're now facing the opposite direction and the kite is semi-wrapped. A smooth pull should flip the kite back into a normal flying orientation. I will refer you to
this description from
The Depths of Time.
Almost anything else takes up more airspace than you'll have available with an indoor setup.
