If not for these two,  
 
I’d name these the best ‘grump and nutcase’ duo in family media.  
_{And just like Zazz, I ship Sonata with a heroic character from an entirely different series.}

Who sounded drunk

@Casual Brony  
Probably. I could swear she sounded drunk at this point.

With villains like these, who needs heroes?

If these two were a threat to ponies a long to well. That doesn’t bode well for ponies capabilities back then.

I swear, if they did managed to rule the world, they’d probably kill each other after like 5 minutes of world conquest.

That little victory smile from Aria at the end…

Sonata spiked the punch, I’ll bet.

(continuation)
 
Students: “BATTLE! BATTLE! BATTLE!”
 
Adagio Dazzle: “That’s enough, you idiots! Break it up! Save that canned heat after the main event.”  
Aria Blaze & Sonata Dusk: “But Adagio…”  
Adagio Dazzle: “I can’t believe you two stayed up till midnight playing Equestria Grudgefest while I was asleep! Now they’re chanting ‘BATTLE! BATTLE!’ on us! (Sighs) But rest assured that we will give Canterlot High more than this close call of a bloodbath.”  
Aria Blaze: “TCH! Hmph.”  
Sonata Dusk: “OKAAAY, Boss.”  
Adagio Dazzle: “If I catch the two of you getting personal again, I’ll be twisting your arms and your necks full 360. Is that clear?”  
Aria Blaze & Sonata Dusk: “Crystal-clear, Ma’am!”

to OP  

Is it just me or she sounded a little tipsy when she said the line about good fruit punch…?

I agree with the OP

“Ha! I messed up your hair a little! I win!”
