Rafisol's character development Version 3

*__All the details you're about to see have spoilers for Puyo Puyo Chronicles__*

Before Rafisol emerges from the pendant, she actually does talk to the main party, twice,

The first time she questions "Why am I here.... why was I born? I don't understand... I don't understand anything...."
Immediately, this hints at one of two things, either Rafisol self-loathes, hating her existence and wishing she wasn't ever born, or it hints that since Rafisol is a being of pure evil (because surprise evil pendant that Ally wears), that she simply doesn't understand anything, I personally like to think the self-loathing one since it gives her character and development more depth
Funnily enough Arle mistakes this as Satan putting on a voice but he's like "That wasn't me."

The second time she warns them that once she reaches the top, she will "take everything." Yep, not just the magic power of all our heroes, or even all the magic in the world but EVERYTHING, most likely putting an end to anything that currently exists.

So when Rafisol appears and Ecolo explains how it all happened (being that the pendant he gave to Ally takes love power and converts it to darkness), Ally asks "If she's from my love, she must have love right?"
Ally's wrong, Rafisol says "Love....? I don't... have something like that....."
So they battle Rafisol to remind her of love. (wow SEGA gr8 buildup to the final boss amirite)
After the battle, Rafisol is weakened. In a bid to continue to exist, she tries to take Ally's power. She doesn't want to disappear, she just wants to continue to live.
She manages to pull some Persona type thing and seems to assume control of Ally, Ally gives up and assumes it's the end for her.
Then Arle and friends come to the rescue with the whole "friendship is magic" thing
Rafisol's weakened, but won't stop, she needs to continue existing, but with the whole friendship and love power thing it doesn't work.
Rafisol: What is this.... i can't.... take it....?
Ally: That's right...
Rafisol: W-what is this power...? l...love???
(Probably some dialogue in between)
Ally: I understand, you wanted to love... isn't that right, Rafisol?
Rafisol: I don't know... I'm an evil existence... so... (Keep this statement in mind, it shows up later)
Satan/Dark Prince actually saves Rafisol's life, he gives her power to exist. Why? As a thank you gift for giving him a fun trip with Arle (GG Satan/Dark Prince)
Ecolo returns Rafisol into the pendant, she still exists though yay (Can she can come out of it by herself or does Ally control that? Is it like a pokéball lol?)
After the credits, we see Ally walking, and she looks down into her pendant, where Rafisol is, at first Rafisol appears to not like being in pendant, eyes closed looking annoyed, she then folds her arms and enters a post somewhat similar to her win pose, but then she looks up and smiles at Ally, blushes and everything, whilst giggling (AND MY GOD IT'S AMAZINGLY ADORABLE) so we can see that Ally has managed to bring happiness or love to Rafisol and she's enjoying it.

Now, on Carbuncle's & her own master quests, she gets more development
In Carbuncle's, Arle & Carbuncle started talking about how they wanted to eat curry and Rafisol/Ally ask "what's curry" and Arle's like "WAIT does this world have no curry??!!" and Carbuncle's is all D: about it so naturally Rafisol's reaction is... "If there's no curry here...then if i take over a world with curry...."
So Rafisol knows she can use her powers to help others, but she still can't really tell what she should and shouldn't do...she did just come into existence not that long ago, she knows helping others is good but still can't really tell between right and wrong.
(Also funny that Rafisol's natural reaction is to just take over a world that has the missing item.)
Carbuncle's super happy though and wants Rafisol to do it
Arle doesn't want that to happen, luckily for her, Amitie's here to save another world from being TAKE OVER
Amitie: AAAHH let's switch the topic! Like! About puyo battles, or something!
Carbuncle: Gugu guu guu!
Arle: Carby wants to play you, Rafisol
Rafisol: ...Me? I have... no reason to decline...
At first Rafisol doesn't realise why Carbuncle wants to battle her, she's still showing that she doesn't really understand friendship and all that, but she can understand that there doesn't have to be a reason for friendly acts, as she says she's got no reason to decline something like this.
After the battle Carbuncle said he wants to eat curry with Rafisol someday & Rafisol was kind of smiling about it (ADORABLEEEE!!!) as she's saying "I still don't know what curry is... but someday, if the chance arises..."
This development happens quickly, but it happens well, she's learnt now parts of friendship, love and being together with others and she wants to be able to be around the others at other times whenever it's possible.

Now, Rafisol's quest requirement was to have a puyo battle that was fun and would make her smile, so naturally Ally volunteers.
(Ally's AI sucks at puyo though RIP)
Ally: Did you feel the love?
Rafisol: I don't know...
Rafisol: But... I didn't smile...
Amitie: Does that mean you can't become a master?
Rafisol: I don't think so... somehow, I feel power...
Rafisol: I may be able to become a master like this...
Ringo: Huuuh? Did Rafisol maybe smile while we weren't looking?
Rafisol: No. There's no need... to be here any longer. [LEAVES]
Well, stuff doesn't seem to have worked...or did it? She never felt the love because she doesn't know what it feels like, despite being with Ally for a while, she doesn't truly understand the feelings. Although she claims to not have smiled, she still says she felt power and could become a master. Ringo even brings up the possibility that no one saw Rafisol smile, but Rafisol quickly shuts that down and claims she doesn't need to be around anymore. What i get from this is that she's embarrassed to admit that she actually did smile because of that match, and she leaves so that no one can catch her smiling afterwards. She knows she's an evil existence and because of that she thinks she probably shouldn't feel these things, so she tries to hide it.
Rafisol was (apparently) using the faint smile sprites after she battled Ally but idk if that counts.
Ally talks to Arle about it afterwards and is like, "Maybe, maybe she didn't make a smile, but in her heart, she had fun, and she smiled, in her heart?"
I think this is actually what happened, you can get that fuzzy feeling in your heart even if you're not smiling. Rafisol definitely had fun and got that warm, fuzzy feeling, but she simply didn't know how to express herself, so she hid it and ran off.

Remember that statement I told you to remember?
Rafisol: Why are you... still here? I'm... a dark existence"
Ally: We're already friends!!
Rafisol: I... don't remember that
And finally, Rafisol, realising she's a dark existence, wonders why anyone would ever want to be around her, this further hints (and for me, basically confirms) that Rafisol self-loathes, she knows her existence is evil, but she hates it, she questions why she's here and why she was even born. Believing she doesn't deserve any form of company or happiness, therefore she hides her happiness. However, she doesn't leave the party because she wants their company and wants to feel the happiness. She could leave, and most likely she wants to, but she doesn't want to go to being alone and lonely, where she's left to her own self-loathing, despite thinking that's what she deserves, she wants to experience the happiness and love that everyone else has, and hopefully be able to fully affirm herself that despite being an evil existence, she can just live a nice, happy life with everyone else without any problems and still be accepted without any problems.

EXTRA NOTES:
So after writing this I had a good thought. What if Rafisol's knowledge of herself all came from Ecolo? He explained how Rafisol came to be, and understood enough to realise she's an evil existence, but then that's all she knows, after all, before she emerged, she literally said she understood nothing, not even why she was born.
