She killed all three of them.

Chrysalis went down swinging, no laser beam could tame her pride and anger… But it was not the smart thing to do, even tirek thought she was nuts at this point.

OBJECTION!!!

I’m sure becoming better friends with each other is probably the first thing they’ll be forced to do until Twilight decides on their paroles.

@Harshie83  
Somehow, I doubt that was the deciding factor.
 
@Bunny-CarrotHunter  
I concur. They were clearly capable of it.
 
@Background Pony #9E05  
What were you expecting? The mere passage of time doesn’t make the episode any less dreadful.

@Background Pony #9E05  
Well, I don’t care what anyone says, I COMPLETELY disagree that they deserved their petrification.

@Whistle Blossom  
They’re pretty much the same at this point

@Background Pony #9E05  
To quote Rarity, “we are not whining, we are complaining.”

Gotta love the fact that people are still whining about the finale too this day. Wonder if the guy who keeps uploading screencaps from it is getting tired of hearing the same things over and over and over.

Proud and deadset ’till her last moments.  
….I still love her and genuinely wished the Mean 3 would of remained friends with each other.

At this point, all of Chrysalis’s threats were nothing more than empty. Even if she tried running away, all of Equestria is surrounding them.

@Background Pony #DE96  
This is why until the comics clear things up with this heartbreaking hypocrisy, the real Grogar has my blessings to take back Equestria.

The other two had to suffer because of her decision, think about it

@Harshie83  
Maybe a little of both. Chrysalis was a very proud creature, but she had also spent a thousand years leading the Hive (going off the comics). She also thinks the changelings have been “corrupted,” and that friendship is a “disease.” Also, the ponies only became friends with the Changelings when they reformed, and never tried helping them when they were in their original state. Tirek spent a thousand years in Tartarus, and no one ever tried to reach out to him. Cozy Glow was a filly, and they didn’t even try. And then there’s the fact that Discord, the friend of the ponies, was setting them up to get killed off by the Element Bearers.  
So when you think about it, “friendship” is going to ring hollow to these guys. But let’s face it, the ponies didn’t try very hard. And what was done to these three makes me wonder if the ponies really are as virtuous as they claim…

Sometimes I wonder if she (and the others) understood what Twilight was saying and just didn’t buy it, or if it just went in one ear and out the other.

@Background Pony #DE96  
I wish he had.

@Harshie83  
It would have been funny if Thorax interrupted her instead: “Shut up, Mom, it’s over. We’re taking you home.”

“Yes, I’d love to make you all mad enough to turn us into statues, so here’s a rant.”

Tirek: Dude… shut up.
