What does Chapter 5 say about the interaction between Devidas and a Fakir in Shirdi?

According to the account in Chapter 5 of the Sai Satcharitra, a Fakir was brought before Devidas for a scriptural debate. Devidas, who was very wise and had been in Shirdi for twelve years before Baba's arrival with the wedding party, defeated the Fakir with his detachment. This defeat drove the Fakir away from Shirdi to Vaijapur. It is mentioned that many years later, this same Fakir returned and bowed to Sainath, having had his delusion about being a Guru dispelled through repentance.
