“Daddy, why don’t I have a mommy? Everypony else in Flight School does.” 5-year-old Rainbow Dash asked her father.
“Dashie, your mom, left us,” Rainbow Blaze said.
Dash was shocked. “Left? But why? Doesn’t she love us?”
“Of course. She left because she loved you. But I’m still upset with her decision. That’s why you get postcards from her.” Rainbow Blaze explained.
“Oh. Okay. I want her back. I never knew Mommy’s name. And I never knew her.” Dash's eyes filled with tears.
“Her name was Shimmer Shine. And you do know her, Rainbow. She’s in your heart. Do you want me to tell you our story?” Blaze replied.
Dash nodded.
"Okay. She and I went to high school together. I didn't exactly fit in. Your mother, however, was accepted by the others."
Dash's eyes widened. "But you're the best daddy in the whole wide world!"
"Back then I wasn't. Anyway, one day she saw me, and went to talk to me. That night, we went to go see the Wonderbolts perform."
"The Wonderbolts! They're my favorite! I'm gonna be one someday, and it makes it better that you saw them!"
Blaze chuckled as he continued. "I then asked if she wanted to be my marefriend, and she said yes. A few years later, we got married and had you! But then... she left..." Blaze ended with a small frown.
Dash put her hoof on her father's shoulder. "At least we got to spend time with her. But I didn't get to meet her." Dash's expression matched Blaze's.
Blaze then realized what he just did and straightened up. "She's in your heart, RD,"
Dash brightened up.
She was happy with this news, and she enjoyed Shimmer’s postcards from Baltimare.
But they stopped coming when Rainbow Dash four years later, and Blaze and Dash never knew why.
