You were singing on stage as the ninjas recognized you as they thought you died, you didn't. They don't know you have powers (Lloyd has a crush on you), after your song, you went to say hi

Kai: h-how are you alive?

Lloyd: cry's a little I missed you

Nya: h-how is right.

Cole: we saw you die 3 years ago!

Arin and sora: (sora is the elemental master of technology) (during dragons rising), who is this?

Nya: an old friend
