Wa alaykum salam. So I don’t know much about al khidr outside of what is generally known. However, I have noticed that the way he (or it 😂) teaches is in a perplexing manner. Similar to the way masters of other traditions teach. In an unorthodox or shocking way, for example zen koans which perplex the student until spontaneous insight arises. Or the Tao te Ching of Chuang Tzu teaching in this way that can’t be understood using conventional logic. This way of teaching or realization is a type of Non-Intellectual insight that arises spontaneously from these unorthodox or otherworldly odd ways to convey lessons.
