I actually think that the Prince of Verona has several moments where his words provide a sense of resolution to the drama. Although he had been fairly ineffective throughout the drama, he is able to seize the moment of ultimate sadness to provide perspective and a sense of resolution to all that had happened. This is seen when he suggests that both children were the "poor sacrifices of our enmity." Such an idea brings to light that Romeo and Juliet end up suffering because of the sins of their parents and the social order that encouraged a sense of division between both houses as opposed to unity and reconciliation. In surveying the situation with the corpses of the two children littering the landscape, the Prince assesses this situation with a certain bleakness that helps to provide a sense of conclusion to the drama:
A glooming peace this morning with it brings.
The sun for sorrow will not show his head.
This helps to emphasize that the "enmity" about which specific reference was made does not construct a setting in which there are "winners." There is only the reality of loss, helping to underscore the overall themes of the drama. This helps to provide another moment of resolution that the Prince offers in the closing of the drama.
