She does. She really does. Funny thing is that I'll never hate Bloom as a character for this, though. I'll always hate the writers for it because that's handling her character very poorly.

Remember when Tecna proposed that they tell Faragonda about Selina's visit? Bloom basically shut Tecna down with her almighty Winx leadership authority and that was terribly out of character for her. It's not like Bloom to just silence one of her best friends just because she's recognized as their (unofficial) leader. That scene proved without a shadow of a doubt that the writers (co-written by Nick at the time) couldn't even have Bloom act in-character for the focus to be on her. Yeah, there are still a lot of moments that RAI wrote that also make Bloom look bad, like in the first movie where, while her best friends are graduating and becoming one with their magical sources, Bloom was brooding by herself instead of putting on a smile to be happy for the friends that she fought alongside with and came to love like sisters. She's never called out on this either and the Winx proceed to risk their lives to revive a lost kingdom just for the chance of Bloom getting to see her birth parents. Knowing Bloom at that time, her feeling bad for herself as her best friends graduate was also pretty out of character, especially given how she never tells them about her nightmare where she dreamt that the Winx were teasing her over possibly never getting the chance to earn her Enchantix. That was most likely done because Bloom didn't want to make Aisha earning her Enchantix into a "woe is me" problem. Heck, Bloom was technically a Mary Sue since Day One since, after just finding out she was a fairy, she later finds out that she's the most powerful fairy/magical being in the entire Magic Dimension (excluding Darkar). She may have been hindered by the fact that she didn't know how to use her powers but she still held the most powerful source of known magic within her nonetheless.

Basically, Bloom's being a Mary Sue is based on poor writing. Daphne didn't have to be retconned just to give Bloom yet another dead relative that could be brought back. Musa still has to accept that her mom is long dead, which is why she never uses her Sirenix Wish, and Stella has to accept that her parents will never remarry, while Bloom now has two sets of parents that are happily married. Bloom getting everything she wants is a problem that the writers keep making and that's why people think Bloom stinks. Again, I'll never hate Bloom but I'll always hate how the writers poorly handle her character.
