[@Lugubrious] I assume -according to the info - that Geno can create a friend heart to free Mario from his corrupted state?

Like, Geno's rushing towards Mario - ready to kill - but then rejects and unintentionally reveals a friend heart that ultimately revives the plumber upon colliding with him? This is viable right?

How would he know how to? Making a Friend Heart requires a specific action, and to do that accidentally would be one heck of a coincidence.
