Based on the episode where the girls's mothers come to visit. Musa is reeling after she see's all the others spend time with their mothers, and she watches everything standing alone. Flora comes and cheers her up, acting as a mother/sister figure to Musa, giving her a shoulder to cry on.

A:N/ I'M SO UPSET THAT NONE OF THE GIRLS WENT TO HER, I'M GLAD FARAGONDA DID, BUT FHFHFHFH. THIS IS A FIX IT FIC

Musa raised an eyebrow when she saw a flower appear in her hand, then she heard the sound of a portal opening. She looked up, and felt her heart slowly shatter all over. It was the rest of the winx's mothers. Her throat suddenly felt rough, she was unable to swallow, her eyes stung, she was unable to look away when she watched them hug each other. It felt difficult to breathe, to speak, she couldn't move as fresh grief ripped over her once again.

The fairy of nature, after hugging her mother, pulled away and noticed her friend stand there. A wave of sadness coursed through her, as she looked at her mother. Her mother had noticed Musa too, and felt the same wave of empathy. She nodded in understanding and let Flora go to Musa.

Flora made her way to the Fairy of Music, and cupped her cheeks, making the grieving winx look at her. Flora frowned, her heart breaking at her expression, and wrapped an arm around Musa's shoulders, her other one holding Musa's hand which was curled on her abdomen, with the flower still there.

Both fairies walked away from the group to a secluded open space behind the campus. They stopped at a tree, and Flora gently sat them down. "Oh, Musa..." she murmured, rubbing the fairies shoulder. She could still tell her friend was holding back her grief.

"Let it out, muse." It was the exact right words to say, because she suddenly felt Musa's body start to shake uncontrollably, and she could feel wetness and the faintest sounds of sobs. Flora pulled Musa down to her lap, and ran her hands through her dark midnight blue hair, letting her friend cry her grief out.

Flora curled around her protectively, while letting some plants grow around them to form some sort of shield. Her heart shattered even more when she heard pleas of "I miss her...I miss her so much..I want her back."

She rocked Musa back and forth, tightening her arms around her whispering words of comfort. "You're going to be okay, Muse." she brushed her fingers through her hair once more as she rode this out with her. She felt horrible, knowing how many mothers days Musa rode out by herself when she was little. But now that Musa was apart of winx, she made sure not another goes by with her by herself.

Flora looked down at the girl in her lap, whose shaking ceased, but was now hiccuping. She kept her hold on her until Musa decided to sit up. It took about 15 minutes or more until she finally did. Flora furrowed her eyes in the most gentle way, as she brushed strands of hair that stuck to the music fairy's face.

Musa hiccuped more as she shakingly smiled at Flora. "You...didn't have to flor.." Flora shook her head. "Muse, I wanted too, it's fine, you really looked pained, and I wanted to be the one to comfort you..you needed it, sweetheart"

The music of fairy said nothing but hiccuped and wiped her swollen cheeks. "Thank you so much for being there for me...flora."

Flora pulled Musa in for a tight hug, which she returned, and kissed the top of her head. "Always..."

Since Flora is the most understanding, I picture Musa going to her for comfort, if not, Flora goes to her first then comforts Musa. Also they are an underappreciated friendship, and i'm disappointed that we didn't get to see more.
