Ooh, great question! I think Pantalone would be deeply scornful—to the extent that Celestia’s acknowledgment of Dottore’s ambition might actually make Pantalone think less of him. Their partnership feels very “you and me against the world,” so I think Pantalone would see the Vision as a threat on a fundamental level. Deep down, he would also be jealous and petty... not that he’d ever deign to admit it.

If Pantalone were to receive a Vision, Dottore would laugh until he can’t breathe (very hehehoho of him). Pantalone would be furious by the Vision’s sheer existence. To receive one NOW—after having been overlooked and destitute as a child, after having taken control of the very lifeblood of the world through nothing more than his own mortal power—would be beyond patronizing. It would be a divine insult.

I often joke that Pantalone’s Vision story would be a more dramatic version of Keqing’s in which he would try to destroy it in increasingly violent ways. Dottore would be cackling gleefully at his side, raving about how perfectly amusing this all is and mocking Pantalone for finally having earned his precious Morax’s approval.

Either way, Pantalone would not be pleased. He wants power, but he wants to take it on his own terms. Having it be willingly offered by the gods after all he’s been through would quite possibly destroy him.
