Look, I'm kinda coming into this out of nowhere since I haven't read the oneshot that you're talking about in this thread but I just wanted to comment on something in general here... in writing, well, we all know that part of the name of the game is getting your readers to feel some kind of emotion. But here's the thing... people in general don't like to be emotionally manipulated. So, as a reader, if I really feel like the writer is working hard to make me feel sad about a character (particularly if I don't think the situation warrants such dramatics) then I'll disconnect with the character even further.
If you want to show a conflict between Ariana and someone else and you want to show that she's in some way effected by this, you don't need to use broad strokes like having her break down or physically assault someone. In fact, she should probably be giving as good as she gets most of the time, at least from my perspective. If all she's dealing with for insults is generic stuff like "lying *****" and whatnot, then she should be able to easily craft witty comebacks to deal with the situation. If an insult from her opponent actually goes beyond basic name-calling and actually extends to something that she's sensitive about (because that's where the real payload is to the situation. Just having her react to garden-variety name-calling isn't particularly worthwhile) then you can show that it effects her in small ways. She narrows her eyebrows or absentmindedly clenches a fist or takes just a moment longer to give a scathing reply than she would normally have. Then the reader can see that the comments do hurt her. But we don't see her as any weaker because of it. We see that she can overcome.
And, I don't know, because I'm not going to claim to be an expert on Ariana's character or anything. But I generally find an "I demand respect!" line to be more in line with toadies who shouldn't necessarily get respect. So Ariana shouldn't ask for respect--she should do things that make her respected.
