Consider the relationship between Dante and Virgil.

Dante and Virgil’s relationship starts off as a guide and a follower. Virgil being the guide and Dante being the follower. Dante being lost in Hell seeks guidance and Virgil comes in the form of a guide. Later on as they move through different circles of Hell, Virgil takes the form of a teacher because he educates Dante of different punishments of the different circles in hell. Virgil sympathizes with Dante because Dante felt pity for the poor souls who had to face the punishment of hell. Gradually Virgil’s relationship with Dante turns into that of friendship.
