He found them
καὶ ἐλθὼν πάλιν εὗρεν αὐτοὺς καθεύδοντας, ἦσαν γὰρ αὐτῶν οἱ ὀφθαλμοὶ βεβαρημένοι.
This is almost word for word in Mark, chapter 14:40, but there is an addition about the apostles being embarrassed and not able to say anything. In Luke, chapter 22, and John, chapter 22, there is nothing more about these 2nd and 3rd visits of Jesus. Matthew and Mark recount that Jesus again came (καὶ ἐλθὼν πάλιν) and found his 3 disciples sleeping (εὗρεν αὐτοὺς καθεύδοντας), because their eyes were heavy or overburdened (ἦσαν γὰρ αὐτῶν οἱ ὀφθαλμοὶ βεβαρημένοι). This was the 2nd time that he found his 3 trusted disciples sleeping. There were no excuses, except that they were tired. They had failed to stay awake and be vigilant.
