How does the relationship between Virgil and Dante change throughout Inferno?

I
would argue that the relationship between
Dante and Virgil doesn't change that much over the
course of The
Inferno. When Virgil first appears in1, he offers to help
Dante,
who has been stalled by the she-wolf blocking his path to the hill (Heaven). Virgil
tells
him that he knows another way; it involves traveling through all of the
circles of Hell, but
Virgil promises to be Dante's guide and
companion.

As Virgil leads Dante
through the vestibule of
Hell inand all of the nine circles that follow, he repeatedly prepares
Dante
for what he is about to see and protects him from those who question his presence
(since
he is not dead nor damned yet). Virgil tells Charon, for example, that
it is not his place to
question what God has deemed necessary. Dante faints
repeatedly, overcome by his fear and
disgust, and Virgil supports him and
helps him move on to the next level.

Finally, in the last
ring of the ninth circle, the poets see Satan and the three worst
traitors of
historyJudas, Brutus, and Cassiuseach placed in one of Satan's three mouths. To
exit
Hell they must literally climb Satan's giant hairy body. Virgil actually
carries Dante on his
back, symbolizing not only that a sinner must overcome
Satan and sin to get to Purgatory or
Heaven but also that most sinners need
assistance in their quest. As he has done all along,
Virgil helps Dante
complete his journey through Hell and allows him to move on to purgatory in

the next part of .
