S3·E14 Payback

Heartbroken at the loss of Tecna, the five Winx girls go to confront Valtor at Cloudtower. Bloom learns the fate of her real parents, that they have disappeared in the fight against the Ancestral Witches and were presumably killed in the process. In the end, Sky returns with Brandon, saying Diaspro has been banished for her crime, while Bloom departs for Pyros, the Island of Dragons, to train herself to become strong enough to fight Valtor.
