Solution submitted. Thus far, this thread does not include mention of what I would consider to be Harry’s greatest weapon.
He hasn’t just been practicing “partial transfiguration”. He’s been successfully practicing discarding any notion of time, space, object or causality, in toto.

I can’t bold that big enough.
“End” can also mean “goal”. This is somewhat interesting in light of EY’s work at MIRI.
