What I mean about going in circles is a bit more literal. Since chapter 31 they've:
1: Got spotted
2: Used magic to fight back
3: Run away
4: Got spotted again
5: Disguised themselves
6: Got spotted anyway
7: Fought back with magic
8: Run away
9: Got spotted
10: Disguised themselves again
11: Got spotted anyway again
12: Run away
13: Fought back
14: Run away again
They keep trying the same things, and they keep not really working. 😛
I get that having Tifa learn of real danger would be an important character development, but I don't see how this is going to accomplish it. She says "I've decided I'll never be captured again," with dead eyes like she's determined to do things herself, and then proceeds to get captured, and is seemingly just fine with it since she's playing board games with her captures shortly after. From the start, she's jumping in to save someone else, and says that she'll go her own way if it gets too dangerous, but never does.
Perhaps it's just me, but rather than the lesson being "Tifa learns her place," I'd be much happier if she ends up saving the day with her own strength and showing that she's capable of growing up and making her own decisions.
