"Hey kids, this is a story about your dear old mom and how I met your fathers."

The two kids sitting on the couch stared blankly at her as Caroline smiled nervously at them. The realization of what she'd just said had dawned on them, she knew, but they were so surprised by the statement they could do nothing but stare at her in stunned silence.

"I know... I've never told you that you have different fathers-"

"How is that even possible?" Knox asked, interrupting her. Glancing over at his twin sister, he raised his eyebrows and looked back at their mother in reproval.

"It's... complicated," Caroline admitted, smiling a grimacing smile and sighing. This was going to be more difficult than she'd imagined. She'd put off telling them this long, and they were teenagers. Teenagers were able to ask many more questions than little kids. She should've just manned up and told them when they were eight like she'd promised herself she would do.

"Apparently..." added Piper as she looked down at her hands and raised her eyebrows as if she'd only been saying the word to herself and no one else had heard it.

Standing from her chair, uneasy in the growing awkwardness among them, Caroline planted her hands on her hips and paced back and forth in front of them. "Listen, this is hard enough for me to tell, so just let me tell it, okay?"

The twins gestured in unison for her to continue, and she took a deep breath.

"It all started with a blizzard and a mechanical bull."
