Yeah, it wouldn't be that complicated to introduce the story of Zatanna's mother even if they adapted it to be closer to the comics, just show Giovanni's battle with whoever he was fighting, then him being healed by C̶i̶n̶d̶e̶r̶e̶l̶l̶a Sindella (And of course, show both in shitty slideshows
), then explain she was thought to be dead, turns out she isn't, then they go to the Homo Magi city to kick some ass, with the way the episodes are slower paced now, this story could easily happen if they wanted to, specially since it could help develop Zatanna and show more of YJ's magic side.
