"Harshwhinny cuddling Chickadee during a thunder storm"
I-I couldn't resist...
That one... actually kinda makes sense. I mean, I've even seen a headcanon that has them be the Prince and Princess mentioned in Hearts and Hooves Day, with the Love Poison being part of the explanation of how Chrysalis became a twisted husk feeding on love, and Sombra a ruthless tyrant. It's crazy how much it's credible.
Octavia x Vinyl
Is by far much more likely as I don't think either of them have been pictured together on the show as far as I can remember, and yet it's one of the more popular ships!
So yeah, Octavia and Vinyl are both musicians? Ship it like Fedex.
