Well its weird. Greg's been a single father since his wife 'died'. We havent actually seen Greg being very lonely about it. He doesnt go on dates, he doesnt try to woo any of the ladies. He's a nice guy who's had to put up with a lot of crap.

Jasper is a warrior, A quartz gem, who fought in the war for earth and knew of his wife to the point of Respecting the enemy. Not even homeworld's armies could defeat the anomaly that was Rose Quartz.. and yet there's Greg, the human who had essentially bested the leader of the crystal gems.

Jasper perhaps having war stories of 'Rose Quartz the Rebel' she's heard of from those who fought her. Greg's stories of Rose Quartz the gentle Mystery woman. Plus the joke back in Story for Steven that Greg "Wants one big woman instead of multiple smaller ones". I dunno why it works when its fluff, it just does.

Long flowing amazon mane is better than giant bushy pink-curls.

And they look so cute together! How can such a wonderful ship be so trash?!
