The manga popped up with the question of whether Naruto was truly dead and if it meant the same for Sasuke alongside questions of where both could be, but I haven't seen any mentions of how Sakura plays into this. She's likely to be on the outskirts of the town or something treating the injured though she could have actually fought Kawaki. If so, we get to see Sakura in action again and, in the unlikely scenario of Kawaki killing her, the progression of Sarada's eyes.
