WARNING: The following contains spoilers for Boruto: Naruto Next Generations Episode 170, "A New Rasengan," now streaming on Crunchyroll.
After Deepa beat Team 7 down with ease, the Boruto anime has placed Sarada Uchiha in dire straits -- especially with Mitsuki left on the verge of death. Though their egos were wounded it was a learning experience as they realized they needed to level up. And so, Boruto decided to train with Kakashi while Sarada's been working with her dad, Sasuke, pushing herself to the limit to harness her Sharingan properly.
However, this training proves to be problematic as her mother, Sakura, doesn't like the toll it's taking on her child, leading to a heartbreaking family dispute.
Admittedly, Sakura is coddling Sarada way too much but she has good reason to as she worries that the girl is harming herself in their father-daughter sessions. Sasuke obviously won't let her get seriously hurt but what irks Sakura is that Sarada is trying hard to improve her eye endurance so she can hold the Sharingan longer. This might even lead to the upgraded Mangekyo Sharingan emerging, and seeing as it's tied to tragedy, evidenced by the likes of Itachi and many other Uchiha clan members, Sakura doesn't want it happening.
In fact, she thinks these arduous sessions are endangering Sarada's body and mind, causing the teen to flip on her mom as she senses distrust from her. Sasuke, however, wants to treat Sarada like an adult and a shinobi who must be ready for war, but this dredges up painful memories for Sakura as nations have lost many people thanks for the likes of the Akatsuki, Madara and Kaguya attacks. Factoring in all of this, she thinks the family's destined for darkness as they're trying to go back to these bloody ways, rather than the current peacetime that they should be enjoying right now.
Clearly, Sakura is suffering PTSD from her time in that era of child soldiers and even though she's a senior medical ninja with a family of her own now, those memories feel like yesterday. Sasuke picks up on these insecurities, recognizing that Sakura feels like she was weak back then and if Sarada shows a similar weakness while leveling-up, she'll die. Seeing as Sarada has Sasuke's fiery ambition, she prefers the girl not to try; to stay home rather than venture out, brave and bold, into battle. Sasuke isn't a fan of this denial or aversion to danger but with his newfound sense of empathy and compassion, he reassures his wife and assuages her concerns.
These extraneous considerations don't impair Sasuke's judgment at all as this is the natural course of Sarada's career. What he does have to do, though, is make Sakura feel more important and loved, and maybe even suggest that she help oversee the training, too, as her medical expertise can aid with Sarada's recovery and endurance -- especially for her eye. Whether Sakura and Sarada can repair this current lack of optimism is another question, but with Kara and sinister affiliates on the loose, Sasuke knows they'll have to do so sooner rather and later.
