Well, Rose, Daphne only helps, if the Winx asks for her help. In the "Bloomix Power", she just really wanted to help the Winx because they're powerless, so she did everything she could to help them. In the "Vortex of Flames", Aisha asked who are the Fire Eaters and Stella asked her how to defeat them, so she answered them both. In "Attack of the Sphinx", she told the legend of the Mummies because Bloom asked. She also told them the legend of the Sphinx because Flora asked what it is and because she wanted to clarify to Stella the dangers of answering its riddle. She also only said the legend of the Green Dragons because maybe she could calm them by telling that they are friendly creatures. She also told them the weakness of the Children of the Night because Bloom asked.

It's their fault, for not asking Tecna. And it's they're fault for not knowing. Not Daphne.

Don't get me wrong, Rose.
