Agreed! Green Beetle is probably the unknown disturbance that was triggered in the current timeline, as Bart said, there's no record about the mars scarab

As Blue Beetle does go evil in Bart's original timeline in the future without green beetle, green beetles participation in this timeline may not make blue evil, or could be the thing that still puts blue beetle back to the evil side, as impulse changed the current timestream when he joined the team... im not very good with this timestream concpet but this is how im perceiving it... ish lol

Also remember with Miss Martian's psychic link, she was shown things green beetle volunteered as she was too scared to go through his mind, so he could possibly hide or alter his own memories. And who knows how the scarab has affected the martian physiology, as that fact is mentioned so often as to how green beetle actually 'controls' his scarab
