They got married a few years later, until Sunset became pregnant. Surprisingly, Comet seemed ecstatic about this, but Sunset was in complete shock; they were too young to be parents already. But she decided to go through with this, for the sake of their happiness.
About 9 months later, Sunset and Comet had a son, Blazing Glory. But a few months later, Blaze began to resemble a familiar guy Sunset used to go out with. Comet was outraged, and he accused her of cheating on him. Sunset tried to explain that she and Fire Streak were just friends, and she tried to explain genetics to him. Sadly, he wasn’t the brightest guy at Canterlot High, and he left the next day. They got divorced, and Sunset was crushed. But this time, she wasn’t alone.
She raised Blaze all on her own, and sometimes had help from her best friend, Fire Streak. Eventually, they fell in love again, and about a couple years later, they got married. They were so happy together; they even had a daughter, Autumn Sun.
20 years later, Sunset started writing to Princess Twilight about returning to Equestria. She missed Equestria so much; she never realized how long she was gone. She and Streak had a long talk about it, after lots of explaining about Equestria, ponies, and magic; Sunset wanted to go home, but she wanted to take Blaze and Autumn with her. Streak was shocked, but he didn’t want to argue; he completely understood. They decided to let Blaze and Autumn visit him once a month in the human world.
However, explaining this to her children had intrigued and confused them completely. They talked about how ponies in Equestria didn’t know anything about humans (except for the princesses and the mane 6). They arrived in Equestria through the mirror, in Twilight’s Castle. Twilight and her family gave them a warm welcome, but in other parts of Equestria, there were still ponies who detested her for what she did. There were silly rumors being told about Sunset’s plan to overthrow Twilight.
After a few days of searching for the Wonderbolt Fire Streak, he wanted nothing to do with her or her family. But she always had the human Fire Streak in the human world, and that was enough to keep their small family together.
