Last time we saw Alexandros as an old man, growing his grandson and himself in one person. Yep, he is Grandfather to himself.

When Alexandros the yang visited his Grandfather on his summer holidays, he went to the Holy River Gang, and was eaten by the Holy Crocodile. So he never visited the future, never come back and he didn't gave birth to his father Philliphos, and unborn Philippos couldn't give a birth to him. Errr... CTD?
