Not once have I said they're conclusively the exact same in all aspects. You're misrepresenting my statements.same ≠ similar.
You ASSUME the powers are exactly the same based off of snippets of evidence.
For instance Moonsongs wolf is male and white furred while MC's wolf is black furred and female.
In other words OBVIOUSLY not the same, but similar.
What OTHER DIFFERENCES are there?
We know that he can make his hands glow green and shoot green energy. Whether or not it has the same possibly devastating effects as Emeralds power is completely unknown. He made her TV drop from the wall, but that's it.
The clone appears to be the same ones as Kat can summon. Thing is it is completely unknown whether or not it behaves the same as hers, simply because she did not disclose most information about it. For instance is the clone completely dependent on Kat and her brain or does the clone have some level of independence? Meaning can she TELL her clone where to go or can she only SUGGEST where the clone should go.
The fact that some things are the same does not mean that everything is the same.
And frankly, your own statements conflict. For something to be "completely unknown" it'd have to have absolutely no evidence to support it. But you included several pieces of evidence that the core function are at a minimum highly similar rather than wildly different in your response. Therefore, it's not completely unknown.
In either case, if we want to talk about speculation, there's far more evidence of core similarity than difference. Therefore the theory that the powers work fundamentally the same is much less speculative than that the powers work fundamentally different.
And again, none of this changes the fact that MC viewing Marina is not inconsistent with the evidence we've so far seen regarding how Evelyn's power work, which is what kicked off this whole discussion.
P.S. Regarding the wolves, from a different perspective they differ very little. Moonsong's wolf is the opposite sex of her. Therefore, the fact that MC's wolf is the opposite sex of him could be interpreted as similarity rather than difference.
