If someone told me that we’d see a continuation of the A and B’s backstory this chapter, I would’ve said they must be pulling my leg. Luckily no one did, as we had a full chapter of backstory with more to come later on. I figured Bee got his point across with the fist bump last time, and the flashback was simply intended to illustrate how they’re able to communicate without words, but the latter is shaping out to be the message itself. However, it does appear that Bee is trying to tell A why he’s so supportive of Naruto, or more specifically, to remind him of the hardships that a Jinchuuriki has to go through. The minor plot twist of sorts was their encounter with Minato of course, which at a minimal, emphasized that A knows first-hand just how fast the late Fourth Hokage was. After I went on a bit of a tangent about speed last chapter, it’s almost as if the story wanted to make it clear to readers like me that yes, Raikage is pretty darn fast himself.
Naturally, that was overshadowed by the immediate show of respect on Minato’s behalf after realizing that he’s up against a Jinchuuriki who’s very much in control of the Tailed Beast within him, followed by the cryptic words of advice he gave A before he retreated. Quite frankly, I don’t really care to speculate about something that will probably be explained in the very next chapter, but my initial hunch is that Minato was advising A to learn what Bee is using to fortify his resolve as a Jinchuuriki so that he can support him and prevent him from falling into a state of despair like those before him. For Bee, this is likely A, whereas for Naruto, it’s all the friends he’s made and will do anything to protect. All of this sounds rather contrived when I put it into words, but the idea is that A would see his friendship with Bee as a means of relating to Naruto and his frantic desire to join the front lines. Naruto probably feels he wouldn’t have overcome the loneliness of being a Jinchuuriki without his friends, much like Bee does without his “bro” A. The sentimental aspect of that hunch is a little cheesy, but it does send a meaningful message to young readers like I’ve come to expect from this series.
Okay, that’s enough speculation for now.
