I like some aspects of her personality and she is pretty, but the best thing I find about her is her humor.

^ i agree i like her humor too

^^ I agree too. She always makes me laugh.

I like almost all about her. She looks very beautiful, also she's funny and a good and true friend, even she's sometimes a little bit... unfriedly.

Both, and I agree with @lovebaltor: her humor. :D I always laugh at her a lot. xD Season 5 episode 9: Gem, of Emphaty: Stella xD
And in my opinion she is the prettiest, and I like her personality: she has got a lot of flaws: at least--she is Not Miss.Perfect....
I love her so. ♥

Her appearance and humor gained her number 2 on my fav list recently.
