That makes sense! After Steven got Jasper pregnant in the past(because he time traveled) and Jasper gave birth to Onion, but because Jasper's selfishness she kept her Gem and that is the reason why Onion doesn't have Jasper's Gem, but after that happened Steven erased their memories so Jasper didn't know..

THE END
