Sixth Sense on dm29.deviantart.com
I still love the Jackie Lynn Thomas character, and I made it a point that I needed to include her in the series, being Marco’s first love with Star as instigator. Something they needed to straighten with Jackie so there’s no tip-toeing around.
Some minor details about this AU, since some of you asked:
The Battle for Mewni happened. (S3)
Star dated Tom and broke up, but never rekindled the relationship. (S1/S3)
Marco dated Jackie. Just Friends happened and so did Starcrushed. (S2)
Jackie and Marco called it amicably soon after Star left Earth.
Marco and Star visit Mewni and Earth constantly.
