As for the Salad's mum thing, it'll be Sakura. Just Kishi throwing in a red hairing for some dorama. Reminds me of Kushina's ''find a grill like me'' line.
People saying Nardo is a bad dad, I don't get it. Bort was acting up a little in 700 but we can presume that was simply because he was adjusting from having his dad all to himself one minute and then less the next. Kids act up at that age. Sauce was always going to be a terrible father but I'm sure we'll get some bs greater good excuse from Uchiha sympathizer Kishimoto.
