So, however you may have viewed the Tournament prior to the Donamite, the Don/Club Battle, it certainly handled one aspect brilliantly in my view, and that was Sommeliershipping. The particular scene I will recall is BW042, where we see Cabernet confess to herself that Dento really is a better Sommelier than her, and her mellowing towards him slightly in the closing scenes.
I'm going to keep that in mind when composing my analysis.
(The hints are not fact; just my opinionated musings. Please don't take it the wrong way).
BW070: The Donamite begins. We find out that Cabernet is still a C-Class Sommeliere, Dento battles Grace and proceeds to defeat her, and Cabernet's opponent for the first round is Iris. Now, the romantic elements, or just my musings, oh well. Firstly, Dento is as cordial as ever to Cabernet in their salutations, which naturally infuriates Cabernet. Now, there's nothing lovey-dovey about that, but it's still fun to note how angry she allows herself to become with him. It is intriguing to say the least, and it occurs often enough.
The scenes I like are, firstly the one during Dento's battle. It seems initially that he's not faring so well, and Cabernet orders that he simply can not lose, as he is to lose to her. It is cute that she doesn't want him to lose, even if its just to lose to her. However, what I really like about it is that he replies, as there are similar occasions where Cabernet calls out demands and threats at him from the sidelines, and he ignores her. He also stares straight at her and cheerily replies that he won't. He doesn't- Cabernet isn't so impressed, but may I add, she has a blush on her face.
Secondly, it must be when the preparations for Iris VS Cabernet begin. Cabernet calls out to Dento, and requests him to taste her improvement with his eyes. Dento, cordially beams and sets her with the smooth-talking line, "Yeah, I'm looking forward to it." Oh, you Dento.
Anyways, the portrayal of BW042's development? Subtle, very subtle. Cabernet grows angry but tries to blow it off with a "hmph!" instead of allowing it to get at her nerves, IMO. In addition, Cabernet asks him to taste her. She must value his opinion if she especially desires him to view her strength, and evaluate it with his eyes.
BW071: Cabernet loses against Iris.
Em, what is quite noticeable is Dento watching Cabernet very closely. True, he did undertake what was asked of him, but he does it to the point of hardly cheering for Iris, his travelling companion. Another aspect is Cabernet's Dewott learning Revenge in order to gain Revenge on Dento. Bit obsessive, but that's Cabernet's style. XD
What is clear in development is her trainer skills. But, even as a character, she's quite calm, and collected for most of the match. And she does bother to taste Iris somewhat (even if she says she won't do it thoroughly or something along those lines), unlike Ash with Palpitoad (which she hadn't tasted before). But that hasn't much to do with Sommeliershipping; it's just good for her character. We don't really see any more interactions or mentionings after the Cafe scene.
BW072: Dento is defeated by Kenyan.
Hilarity wise, it's full of life, but for Sommeliershipping, it's another story entirely for me. I'll be succinct as I can be; there's no mutual interactions between the pair, Cabernet is onimous but that's focused at everyone, Dento ignores her (which, when given that's she's not exactly saying beautiful things at him would be expected, however it's just depressing as he does answer her in BW070, however it is on his honour... who knows...), and the lines directed at Dento from Cabernet's mouth aren't exactly beneficial. "No-good Sommelier" isn't a phrase
I'd use to display Cabernet's development towards her rival, either.
However, you could argue that she never told Dento her confession; just herself, so she might still be keeping that on hold. Hmm- I still didn't like it...
BW073: Since both of them are knocked out by this point, they are together tasting by the sidelines.
On their tasting- they discuss the raw power of Sawk's karate chop. Cabernet notices Dento's superiority in the command of English on the subject, and growls ruefully. So, though Cabernet knows he's better, it'll still take her awhile to come to terms with it. I mean, she didn't in BW042, really; she looks quite upset as she admits it to herself. But I am fond of that she's not too cheery about it; it shows that this relationship still has a bit to go to blossom (Why wasn't I fond of BW072, then? It was more negative than anything in that department, imo).
Eh, there's not much during Ash VS Masaomi's battle, Dento cheering for Ash, Cabernet making little comments.
In the finals, they do perform a tasting, and again, Dento vanquishes. Cabernet isn't so pleased, even less so when Langley states that he won the Sommelier showdown. (Was she the referee that time? I'm puzzled...)
Anyhoo, my favourite moment is at the end. Ah, sunsets. Anyways, Cabernet promises to Dento that she'll be an A-class Sommelier next time
they meet. The way she words it, though, she tells him that she'll be A-Class one too
, which is cute, that she desires to be an A-Class, and be on the same level to Dento, as an equal to him. :>
