A.T. Robertson Commentary Luke 24:15

"And it came to pass, while they communed and questioned together, that Jesus himself drew near, and went with them." — Luke 24:15 (ASV)

While they communed and questioned together (εν τω ομιλειν αυτους κα συνζητειν). Same idiom as in verse 14, which see. Note συνζητειν; each questioned the other.

Jesus himself (αυτος Ιησους). In actual person.

Went with them (συνεπορευετο αυτοις). Imperfect middle, was going along with them.
