Mentioned it earlier, but basically I am inclined to think that not being the case.
I was highly suspicious of it earlier in the game, but I think evidence points the other way.
The only curious part is why Sauron used Shapeshifter when Lind wasn't even present.
It appeared with all the other abilities, so it doesn't seem to be too fake.
And since it's almost guaranteed that Ekko's flip is doctored, it can be that he controlled Lind's action - Or he's been straight up open buddying all this time.
If that's the case then well.. Don't wanna hear it, really
