After funding out that her longtime crush Big Mac was going out with his new Sugarbabe (I’m calling her that >v<), Pinkie and her girlfriend Gilda brought her to the bar to relax and get over him. There she met Cheerilee. Who was currently drunk and casually spewing her anger about this guy she fancied and was suddenly taken.
The pair share their similar situations and feelings and after a while realise that they were crushing on the same stallion. Cheerilee gets the epiphany to date each other just to spite him. Not knowing what else to do, Marble agrees. (Not to mention how hot she thought Ms. Cheerilee was in a passionate and slightly drunken state). Of course it’s not due to the fact that she finds the rock mare to be absolutely adorable! What are you talking about? Don’t look at me.v’
After several outings parading around in Ponyville, their feelings for each other grew. It became more of a relationship that a thing to rub into Big Mac’s face. Marble eventually gathers the guts to take Cheerilee to the Rock Farm. Her parents immediately go to her with urgent news as she’s been staying with her girlfriend for the last while. She is informed by her father that she has been betrothed. But not to her current lover. Deeply saddened by this she runs and hides in the mines. Cheerilee finds her and offers her to move in with her. So Marble regretfully leaves the Rock Farm to live in Ponyville like her sisters.
They have a small wedding ceremony by Maud’s rock paradise. And despite the odd spell of homesickness every now and again, they’ve been happy.
Later, Cheerilee starts to notice her wife becoming more and more melancholic. Marble loves to help out at the school despite her shyness. But she wants to have her own children. So they decided to adopt. To take on those who were cast away. Like them.
They go to Canterlot Orphanage where they meet their new children. A shy and insecure little dinky boy and an outgoing and adventurous goat kid.
Despite the ups and downs they’ve had (and those yet to come ) they’re a pretty swell pair. ^^
