Aeneas is fired with love of the glory to come for his future nation and he has no more doubts as he knows that it’s fated
he has realised that from the moment he saw Romulus in the pageant and din’t need to answer Anchises when he asked if he still had doubts
We can now see Aeneas’ pietas bearing fruition as the promised world unfolds to him and as he becomes more and more confident in later books of his destiny
The pageant of Rome’s heroes and its message basically guaranteed Aeneas’ victory in wars to come
were Aeneas still downcast about the past he wouldn’t be able to leave the underworld with th air of positive certainty we see in him from this point on
