In this book, we see that Dido is reluctant to become involved with Aeneas, and she has a good reason to be worried. What she doesn't know is that the gods are messing with her fate. Juno's and Venus' "deal" to create a marriage between Aeneas and Dido starts out when the two are out hunting with their friends and a storm hits. They find themselves trapped in the same cave together. This reinforces 2 things: the idea that Aeneas is hunting Dido, and the war between the gods. When we first see Aeneas, he is shooting deer, then in this book, Dido is compared to a doe, and there is a line about "the shaft that takes her life." This refers to Cupid's arrow that makes Dido fall in love with Aeneas, and that love eventually makes her kill herself. Cupid and his arrow falls into the category of the war between the gods, especailly the one between Juno and Venus. Venus knows that Aeneas will have to leave Carthage, and she probably agrees to the "marriage" between Dido and Aeneas because she knows that it will kill Dido if he has to leave. If Dido kills herself, then Juno will be losing one of her most faithful worshipers, and Venus will have won one of the many battles between these two.
