Yes, in the 3rd timeline, Aeroc has no idea about the past, while Kloff in the 3rd timeline is actually the same Kloff from the 1st timeline. He not only remembers the past but is indeed the original Kloff from the 1st timeline.
Basically, it's old-man-Kloff from the 1st timeline jumps/travels to another timeline when everything that haven't happened yet. He meets Aeroc of that timeline.
Do you know where I can read ITRG Vol. 6? I’m currently on the 4th timeline, but I wasn’t able to finish reading the 3rd one.
Question!! In the 3rd timeline does aeroc forget everything while kloff remembers everything? (They restart over-like the beginning of the second timeline) or does the 2nd timeline kind of bleed into the third where they both remember? Or does only kloff remember and Aeroc forgets in the third timeline?
