You can't say no chance. There is no more definitive evidence against it being her than for.
All you've done again is to basically say we don't know who it is or isn't and never will.
Okay, I kind of agree!
The 'balance of evidence' suggest it's not her.
Plus, from a legal perspective, the
"burden of proof" lies wholly on the side of those wishing to 'prove' this is Emma Watson.
If I claimed there is a 40-foot-high gold sculpture of Taylor Swift, on the far-side-of-the-moon, then it's up-to me to
prove it -
not for you to have to DISPROVE it!!!
That is how the world works, thankfully!
So, unless there's definitive evidence that the video is of Emma Watson, then it's NOT!!
Lies and made-up bull-shit don't require 'disproving'!
