There have been young grandmothers featured on previous episodes of 16 & Pregnant, but Danielle's 32-year-old mother Casey might be the youngest. She certainly didn't look like a grandma and when Danielle pointed out her stepfather, Casey's husband, it seemed that initially MTV had made some kind of mistake when they panned to him, as he seemed like a kid himself.
But no, that's really him. This guy is a grandpa.
As for Danielle and her boyfriend Jamie, they fell in love because they have "good convos." Here's a sampling of what they might mean by that. (Count how many times Jamie describes something as "crazy" in a monotone voice.)
