when ariel is looking for melody, she goes in that carern where all her human possessions were but it shows all the items when they were destroyed by triton in the first movie.
Ariel:Oh no sweetie,we're sorry.We should've told you the truth.
Melody:I just wanted to be a better mermaid than a girl.
Ariel:Oh no sweetie,it doesn't matter if you have fins or feet. We love you for who you are on the inside,our very brave little girl.
Ariel: Where did you get this?
Melody: I...I found it.
Ariel: You went over the wall, didn't you?!
Melody: Actually, I went under it. I hate that stupid wall!
Ariel: Melody, you know you're not allowed in the sea.
Melody: But why? And why does that necklace have my name on it?
Ariel: Melody, listen to me...
Melody: You're hiding something from me.
Ariel: You deliberately disobeyed me! I never want you going out there again! Do you hear me? It's dangerous in the sea!
Melody: How would you know?! You've never even been in it!!
This is the second full length Little Mermaid movie. It is not said how old any of the characters are in the movie but Ariel is considerably older.
