Round 5 Elimination: Mulan

There was a tie in votes between Jasmine and Mulan last round but more comments against Mulan so I let that be the tie-breaker. :)

Among all others, she was more pessimist than others, not too though but she didnt have an outright optimistic outlook as well. Like she contemplates it wouldn't be a good choice to marry Kocoum, it wouldn't good choice to leave with John, she questions herself a bit too often.
PS: You've put Belle's name on Jasmine's picture, just to let you know

I don't know why.

anukriti2409, thank you for the heads up! I've corrected it. :D

The others are more optimistic than her.

Although Jasmine feels trapped, she seems very confident and somewhat optimistic about the world outside of the palace and how much she will enjoy it and fit in. It doesn't seem to really cross her mind that it would be too bad or that she'd meet bad people yet she has come across Jafar and other princes with questionable characters. That being said, she doesn't really spread any optimism or cheer anyone else up much and tends to rely on Rajah to cheer herself up.

I think Pocahontas is not as optimistic compared to the other girls though I think it's close with Jasmine. She is wise and takes time to think things through before rushing decisions but it doesn't seem like she really sees either path with much optimism; It seems more of a "which is least negative for my future" rather than positive outlook. That being said, she is very optimistic about the settlers coming into town and making connections between her people and the settlers. She is optimistic about there being peace where there is a war so I see that as making her more optimistic than Jasmine.
