That face, the loss of her kingdom did not affect her sanity, right?
Talking to animated objects again
"I just wanted to make sure..."
"...you saw my best friends rock sculpture from there."
"I thought you freed us from Tartarus!"
"Whoever pulled you from there must have been somepony very powerful indeed."
"King Sombra! You have returned?"
"Why did you bring us here?"
"You may call me... Grogar."
"Until Gusty the Great rose up..."
"No offense, you look great."
"But if he knew about you when he was younger..."
"...we have different ideas of what 'temporarily' means."
"I've spent millennia gathering power..."
"...waiting for the perfect opportunity to seize control of Equestria!"
"And watching all of you."
"I've seen each of your humiliating defeats at the hooves of six puny ponies."
"Do you know why they always bested you?"
"Because they are annoyingly lucky!"
"It is because they work together."
"But we shall use their own strategy to defeat them."
"What are you suggesting?"
"I demand that you join me."
"And Equestria will be ours!"
"I will retake the Crystal Empire on my own!"
"And I will destroy anypony who gets in my way!"
"Well, working together sounds an awful lot like make friends."
"...because I know all about that!"
Lemme at him! I'll DESTROY him!
Tartarus hath no fury like a mother with a threatened child.
Flurry Heart tries to be brutal.
If you sink so low as to chain and muzzle a BABY for neighing out loud, Sombra, you truly are as heartless (no pun intended) as the black spikes you create.
