So, I like the idea of Devi beng the possible woman in Kvothe's life as apposed to Denna. Her and kvothe together would resemble a similar story to Lanre and Lyra. They also made a point in the story of The Creation War that Lanre and Lyra were an unstoppable duo. it also says that Lyra had a gift with names that could match Selitos skill whereas Lanre had no skill in names and its clearly obvious that Devi's alar is much stronger than Kvothe's. But thats not forgetting Kvothe's recent training with the Ademre. So he now favors a sword. So together, i believe they have a better chance at taking down the Chandrian and/or Cinder.
