What was the nature of the relationship between King Tutankhamun and his advisor, Ay?

&#x200B;<br><br>There's evidence in the tomb of Tutankhamun, of a parent-to-son relationship with Ay. Tut is most likely the biological son of Akhenaten, yet evidence shows that Ay was the one to close the eyes. I want to know to what extent Ay was close to Tut, did Ay actually want Tut to ascend the throne, or was it truly the intention of Tut's father Akhenaten? Did Ay really want to rule Egypt? Given that Tut died so young, there's a lot we don't know about the king's intentions.
