Hello, Leon Davies here, also known as TheLeondude or just Leondude. Animator, voice actor, writer, autistic British egomaniac, Dark Lord of the Sith etc.
Sunny and Izzy seek out the legendary Twilight Sparkle on some advice on where to find Opaline and make a friend out of her the same way Twilight made friends out of foes in the past. They find out those foes didn't become friends willingly.
Apparently, Celestia spent so much time training Twilight to wield the unlimited power of friendship, she had forgotten to teach her how to effectively run Equestria. Such as proposing a new tax policy.
