In the crusader clubhouse, two crusaders were sitting at the table, having a somewhat intense discussion.
“Ok, so you and Rainbow Dash are technically sisters,” Apple Bloom said slowly. “So she’s getting married to my brother, so that means she's my sister-in-law, and so Mac's your brother-in-law. And so that makes us…” Her voice trailed off, and she scratched the back of her neck. “Cousins?” she guessed.
“I don't think so,” Scootaloo said. “Cousins are kids of aunts and uncles, not brothers.”
“Second cousins?”
Scootaloo made a face. “I don't even know what that means.”
“Third cousins once removed?”
“Now you're just making things up,” Scootaloo accused.
Apple Bloom scowled. “Am not.”
“Are too.”
“Am not!”
“Are too!”
They glared at each other. “Fine. We'll ask somepony else,” Apple Bloom said. She stuck her head all the way out the window. “Hey, Big Mac!” she called.
Macintosh glanced up.
“When you marry Rainbow Dash, what’ll that make me and Scootaloo family-wise?”
Mac chuckled. “Technically, you won’t be.”
“Aww,” Apple Bloom said dejectedly.
“Hey, now. Family ain't who you're related to…” he started.
Apple Bloom sighed. “It's who you make it with,” she finished. “I know, I know. Fine.”
Mac waited until Apple Bloom had turned to go back inside before answering. “But you can be honorary sisters,” he suggested.
Their ears pricked up.
“Honorary sisters. I like the sound of that,” Scootaloo said, nodding.
Apple Bloom cheered. “New sister!” And she reached out and grabbed Scootaloo in a tight hug.
“Ugh! No hugging! Apple Bloom, let go! I don't care if we're-! Let-! Apple Bloom!”
