How Sarada uses her Sharingan twice in battle against Kara inner Boro reveals how Sasuke's absence in Boruto has affected her on the battlefield.
It's no secret that Sasuke hasn't been there for his daughter Sarada (or his wife Sakura) in Boruto, but how Sarada uses her Sharingan in battle shows the negative affects Sasuke's absences have had on her - especially on the battlefield.
From chapter 2, Boruto made it evidently clear that Sasuke was rarely there for his family by showing how excited both Sakura and Sarada get whenever the legendary ninja shows up. Later on, Sarada even confesses to her fellow teammates how she always gets frustrated with Boruto because of the gripes he has with his father since his complaints are nothing compared to what she experiences with her dad. In fact, Sarada even goes so far as to say that she sometimes imagines what it would be like to have Naruto for a father.
But the ways in which Sasuke's absences have been affecting Sarada's fighting capabilities are alluded to in Boruto chapters 41 and 42 by creator and supervisor Masashi Kishimoto, artist Mikio Ikemoto and scriptwriter Ukyo Kodachi. When battling Kara's inner Boro, Sarada's teammate and Orochimaru's son Mitsuki asks Sarada to use her Sharingan on some of Boro's Dark Mist that he had captured to learn the true nature of Boro's abilities. Later in the same battle, Kawaki realizes that Boro must be powered by a core that's hidden somewhere on his body and instructs Sarada to use her Sharingan to find the core's location so they can destroy it.
It's clear that Sarada possesses the Sharingan in Boruto because it was passed down to her from her father. As a wielder and master of the Sharingan, Sasuke undoubtedly has the means to instruct anyone in its usage and would have done so with Sarada had he been present in her life. Sarada has already proven herself to be a sharp fighter, so if she had been properly tutored in the art of the Sharingan, Sarada wouldn't have to be told to use Sharingan, she would have known to attempt this automatically.
The fact that Kawaki himself suggests that Sarada tap into her Sharingan adds insult to injury because he had never heard of it kekkei genkai before Mitsuki brought it up and yet had already been able to deduce how it could help them after only having learned about it just a few minutes before. Of course, Sarada succeeds both times, but it's no thanks to her father.
