Adlet has a steep hill to climb to convince anyone—particularly Fremy, who seeks unequivocal proof—that he’s not the seventh brave, even as I remain convinced he isn’t. At this point in the show it would seem like a cheap conceit to make him that, and it makes for more interesting drama when Adlet has to prove something that’s true rather than something he merely believes to be true. That is, for him to be the seventh brave but not even know it seems silly.
While he doesn’t quite manage to convince Fremy, he at least gets her to understand him a little better. Before, she was confused as to how someone so seemingly “average” was able to become strong enough to hold his own against the likes of her and Hans. Adlet, heartened by her apparent interest, answers that question by telling her the story of how his sister and best friend were killed protecting him, and how his master taught him that revenge alone is not enough to be strong.
Rather, one must believe in something to gain and maintain strength. To Adlet’s shock, Fremy is jealous of his belief in something, because after the life she’s lived, including a mother who pretended to love her only to betray and abandon her, taught her not to believe in anything, which is why she distrusted Adlet in the first place.
When she asks why Adlet is so trusting of her backstory as she tells it, he tells her he sees similarities in the two of them, and wants to believe her, so he does. He clarifies that this isn’t about love per se, though he’s blushing while doing so, so I’m sure a part of him wants to believe and protect Fremy because, well, she’s a cutey.
Fremy gives a little more ground by not turning Adlet away, but nor does she stick with him, deciding instead to return to the temple and the other braves. However, she gives him a special bullet that when exploded will tell her and only her of his presence, which means tacit permission to call on her whenever he wishes. What she doesn’t promise is that she won’t kill him next time they meet. After all, he still hasn’t convinced her he isn’t the seventh.
And that’s what remains Adlet’s problem as the episode closes on a battle between him and Hans, whom Nashetania believes to be the seventh, rather than Adlet. Tania believes his innocence, and Fremy is willing to hear him out if he has proof, but Chamot, Goldof, and Hans are eager to kill him, confident he’s the enemy. I’m a little loath to side with Tania, for the same reason I don’t want Adlet to be the seventh: it seems too easy for it to be the shifty and never particularly trustworthy Hans.
