#and we all know Alphi truly does adore his sister and will protect her

[lully-jo]

I have a headcanon as to why Alisaie hates being mistaken for Alphinaud and also why Alphi doesn't flirt around like he did in the Studium anymore.

We all know Ali was the weird girl in school and Alphi was super popular and always showing off for girls in school. Thing is, Ali and Alphi are identical and so imagine poor little Alisaie always being a sort of awkward social outcast and someone comes up to talk to her which is exciting holy shit making friends until they realize it's Ali and not Alphi and they make the most disappointed expression. Can you imagine how fuckin' hurtful that would feel?

One day some girl comes up to Ali thinking she's Alphinaud trying to flirt it up with him and it's the final straw. Ali finds Alphinaud and tells him to stop fucking around because if she has to deal with one more of his little girlfriends she's going to kill him. And he sees the tears welled up in her eyes despite the rage on her face and he understands and never does it again not because he's afraid she'll fight him but because he genuinely feels bad for how it's impacted her.
