Reading the other comments elsewhere about this chapter, most of the them seem to focus on the loud "love triangle" in the room. The part where its pointed out that she still calls Sumire "class rep" than her actual name, kinda shows how Sarada has not grown of that phase of her life after-all this time and doesn't have much self-awareness of her current surroundings. Traumatic as it was to unlock her Mangekyō Sharingan, she can't seem to put aside her aside her emotions and look at the bigger picture.
The part about Boruto's training to master his future skills, and the whole shape aspect about his teleportation technique I'm glad they explained. There's also the bit about how Koji lays out the Divergent timeline weakness of his ability and that he basically has to sift through each one in-order to get glimpse of a good future. The more ripples and changes they make, it will eventually be impossible to keep track of all of them all with how many moving parts are in place.
