Sarada = child of Sasuke and Sakura. She wears glasses, which is odd because an Uchiha's sight is never lost unless traded for the power of the Mangekyo. My theory is this - that because Sasuke is now a wielder of both a Sharingan and Rinnengan, Salad inherited on half of these powers. My guess, Sharigan. The role is now reversed - she can't truly see until she unlocks her sharingan (vice-versa of how it was for previous Uchiha). Now Sasuke left Sakura again after Salad was born to go on a journey of self-discovery. That last scene - he turns and goes to draw his sword in the Shikaku Forest - smiles, lets go of the sword and walks away. I believe that is his other son he had while traveling the world as a nomad. And that son wields the Rinnegan. Essentially making the son and Salad half siblings. If Sasuke had this son with Karin, he too can heal. To summarize my theory, Salad can heal others, have super strength, and use the abilities of the Sharingan. Meanwhile, Sasuke conceived another child during his nomadic travels; a son. If his mother is Karin, then he can weild the Rinnegan as well as heal on a cellular level (meaning his healing chakra is only accessible through his cells/blood like Karins). And so, while Salad stays in Konoha to train with Sakura being her teacher, Sasuke's new journey was waiting for his son to find him so he may train him himself.

Also I think Jugo has been following sasuke on his nomadic travels, silently watching over and protecting him like he vowed to do during the war. But I also think Jugo will a "guardian angel" of sorts to Sasuke's son (saying he has one like my theory does), watching over him and intervening in combat when needed. Maybe even taking him on the journey to find his father, sasuke. And if sasuke and Karin had a son in secret, that also means hes related to Bolt, as Karin is from the Uzamaki clan. This would truly symbolize Indra and Asura reconciling and becoming one entity. Just a theory though.
