Jesus made it very clear in several places, that he was doing the will of the Fathers = Jesus must also have a will of his own then.
So, on that bases of not knowing Jesus's will or wills, we cannot answer your question

The reality that Jesus was going to die, was a reality held by both of them

Jesus spoke/expressed what he was told to say and as he was given the word of God without measure, that then made him the express image of God's person, as you ARE your word = Person/God with all of those words, spirit of Him.
Expressed God (Word) out without measure.
John 17:20-23, pretty much sums it up -> "by their word" (Peoples).............."so that".........all become one as God and Jesus are one = one in word = one in spirit as ones words are deemed as the spirit of them.
(Glory there is 'word').

Anyway, cut to the chase, lets not sneak up on the area that your trying to lead it to, or manipulate it to
