Thinking about how much an older draft of F1 was about Anna feeling like the spare only for F2 to come out and say "Yes, you ARE the spare and are only queen because Elsa didn't want to anymore".
I am a firm believer Anna has it in her to be a great queen, but I HATE how F2 build up to it like it was Elsa's arc of finding a replacement, so she could move to the forest without consequences. That is the literal definition of what a spare child in a royal family is (tbf, it's usually in case of death, but Elsa did briefly die, so I'm still counting it).
Like, godforbid the one thing F2 gave Anna (after Elsa already hoarded their fifth spirit destiny and THEIR parents) would've actually been her own arc instead.
