If all girls were this easy ;0 Berzie inadvertently assumed a handsome stallion’s form.
The mare’s name is Diamond Rose, she was featured in IDW comics in Cadance/Shining Armor story arc.
Berzie’s pony form here is Midnight Blaze’s OC - Midnight Blaze.
What are the odds that mare is also a changeling, and they accidentally share love and become gay- I mean, are harmonized? Because no comely female in a bar just walks up to you and propositions you, that’s a classic DnD trap.
That’s when you wake up the next day in a tub filled with ice and missing a kidney.
