How did Dev react when he finally learned that Baba had attended his Udyapan in disguise?

Dev learned the truth after receiving a detailed letter from Jog, which recounted Sai Baba's explanation of the events. According to Chapter 40, upon reading the letter, Dev was overcome with emotion and his "eyes overflowed with a surge of love." He was filled with remorse for doubting Baba, exclaiming, "Shame, shame! I blamed Sai in vain!" He felt very dejected and ashamed of his own "pride of knowledge," which had prevented him from recognizing the Lord's greatness. This realization transformed his disappointment into a profound sense of love and regret for having misjudged Sai's actions.
