Valkyr does not talk. She does not speak. She doesn't gesture or interact with others.
When alone she sits or stands, sulking in her mind.
Her greatest scar is the one that has sown her mouth shut and chains her tongue.

When in battle she shouts. When the pressure is too much she yells, then wreaks havoc.

When she is being hurt, she screams. If she could cry and shed tears, still none would be spilled.
Her torture has left her as a creature of unrefined, unadulterated anger. Her heart replaced with unlimited fury.

And it is this fury the Corpus want out of her body.

As the Harvester targeted her, her self control reached a limit. The audacity of her torturers to try and recapture her was the final insult. Her mind pushed her to the edge, and Hysteria ensued.

Fact of the matter was, her teammates had long moved further, leaving Valkyr behind to ensure the Data Core would make it to the end of the ship, simply to hold back the enemy forces. She could do that. Push her a little too much and the room shall fall under her flurry of punches.

But when she lost her mind, the adrenaline flowed and only her and the Harvester existed now.
She chased it and swung like a wild animal in it's direction.

But the Harvester is a flexible machine. By the time it was in reaching distance, it would take one second to completely maneuver itself to the other side of the room.

As Valkyr's rush of adrenaline ended and her hands and feet rested on the ground to recover from the exertion, the Harvester had only fire a barrage at her.

As she laid on her back, almost knocked out, the quadruped Harvester loomed over her.
It's observant eye staring right at the Tenno's face, as a familiar voice spoke.

"I remember you…" spoke Alad V.

"Haven't you become truly interesting since your escape… Your emotional state connected to your invulnerability, I shall take great pleasure in finding out how we managed that…"

As the world faded around her, faint sounds of machinery hinted at how she was being carried away.

Valkyr does not speak, she does not talk to anyone.
Valkyr only screams.
