Winx Club, Season 1

Daphne:
You haven't lost your powers, Bloom. Look over there.

Bloom:
That's my parent's house. I mean... my adopted parent's house.

Daphne:
Yes, you were brought up on Earth by two caring and understanding people, who loved you well enough to let you go when the time came.

Bloom:
And I let them down. Same at Alfea, I didn't meet anyone's expectations. I don't belong anywhere.

Daphne:
Bloom, you still are who you were and yur past will forever belong to you, just like your power. No one can take that away from you.

Bloom:
So what happened to me then?

Daphne:
Nothing that doesn't happen to us all. You had doubts, you were afraid. You came to believe that, what you loved most dearly, could be taken away from you. But the truth is, no one in the whole universe could ever steal your past, your dreams, or your magic powers. The witches do not own them. They are yours to keep, forever. Bloom, to recover your powers, look deep inside yourself.
