Comments of chapter undefined of Dragon ball Z: A True Saiyan

I wonder how would Sage handle 21 and Nala permantly fused as one majin naga android and wife of Sage and mother of Mia plus can't Towa managed to bring Sage's and Nalas old enemy from the dead? You know the one Sage had to defeat Ice I think his name was the frost demon with ice ki when they were kids but demonzied and more powerful and gains his legendary status cause I don't think Frost Demons with power of having their ki ice like is normal like how Sage being a Legendary Super Saiyan is not normal but both are rare and be forever Sages arch nemesis?
