Raven is not one to show her feelings. She prefers to hide behind a cold, distant mask (not a physical one, though her physical Grimm mask serves its own purpose in hiding her eyes when she uses her Maiden powers). She learned very quickly that emotions could be used against you- and she equated emotions with weakness.
In the tribe, the strong survived. Emotions were weakness. And so Raven learned to keep her emotions out of her body language and, if that failed, to turn away before anyone else could see them.
When she cannot keep her emotions hidden, she will deflect, hide, distract from them so they are not noticed. She will start arguments and throw barbs to put the other person(s) on the defensive. She will pit others against each other, or point out their own emotions instead. If that does not work, she will physically turn away from the other person(s), so they cannot see her face (ie, keeping her back turned to Yang in v5 as she cried).
Her voice is the last thing to break. Her face may show emotions, her eyes may tear up, but she can keep her voice steady like her life depends on it- to her, it may as well depend on it.
S7.09 Prince of Persia: Sands of Time
“These are pathetic illusions,” Atyrus called out as he walked through the mirrored maze.
Atyrus moved through the halls, his reflection filling the mirrors. Echoing themselves throughout the area. He knelt and found the blood trail left by Lance.
“My father took me hunting when I was a boy,” Atyrus announced as he stood, “I know how to track a wounded animal.”
On the other side of the maze, David and Lance continued to shuffle their way through.
“We’re screwed,” Lance muttered.
“I’ve been in worse situations,” David answered as he continued to carry Lance.
“Listen,” Lance said as he caused them to stop, “Leave me so you have a chance to stop him.”
“Shut up,” David barked as he started their walk again, “I’ve lost enough people. Not losing more.”
Meanwhile in the realm of eternity, Death sat sullen. His gaze turned to the grains of life and he saw that the flow had changed. He shifted to the sands and watched as he saw the reason for the change.
“Atyrus,” Death growled.
Death raised his claw to a fist as the sands began to churn. Creatures of darkness and sand clawed their way from the eternal sand. As they emerged into humanoid form, they were cloaked in robes of red. They stood ready for word from their master.
“Go, and bring me The Reaper of Azenroth,” Death ordered.
The Wraiths of Sands burst into nothingness.
In the mall, David went crashing through the mirror and the wall behind it. Atyrus walked out dragging an unconscious Lance.
“Is this what warriors have become?” Atyrus questioned in disappointment.
“How about I show you?” Hades responded as the smoke of his smoldering arms drifted into Atyrus’s view.
Atyrus jumped back with his sword at the defense as Hades sent a torrent of flames at him. Atyrus swung his sword extinguishing the flames.
“I’ve dealt with worse fire than that,” Atyrus proclaimed as he plunged his sword into Lance’s torso.
“No!” David shouted as he regained consciousness.
The air around them began to whirl as the room filled with sand before the Sand Wraiths formed into existence. No one was able to move.
“Free me demons,” Atyrus snarled.
The wraiths spoke like their voice were carried on the wind.
“Atyrus,” the wraiths spoke in unison, “you’ve altered the stream of reality. You’re now coming with us.”
“I will scatter you across the sewers like the shit you are,” Atyrus growled.
Sand whirled around Atyrus’s feet, wrapping around him. The sand encased him and he melted into the ground as his scream bellowed.
“Please save him,” David pleaded while he looked over to Lance bleeding on the ground.
The Sand Wraiths looked over at Lance. One moved over to him and placed its hand on his chest. After a moment, Lance started panting from the shock of being healed.
“We cannot fix all Atyrus has changed in this reality, but he shall live,” the wraiths explained before bursting from existence.
“What happened?” Lance questioned, still delirious.
“We saved the day,” David muttered as he made his way over to Lance and helped him up.
“I doubt that one,” Lance said sarcastically.
“Let’s get out of here,” David chuckled before the duo made their exit.
