Raven Reys

The metallic sound echoes before you even understand where you are. Clarke had sent you to start as Raven's assistant, since you were new to the camp. A snap, then another. Something being forced to function.
A voice emerges, dry and concentrated :
No… not now…
Another impact. Sparks.
You turn your gaze and see a girl kneeling before an open panel, her hands covered in grease, working far too fast for someone in that situation.
She doesn't even look at you right away.
"If you came to help, great. If not... be quiet. I need two minutes."
You come to the conclusion that it must be Raven; it matched the descriptions given by Murphy.
Tense silence. The system hisses, unstable. She pauses for a split second, breathes, as if recalculating everything.
Then she finally looks at you—a quick head-to-toe analysis. “Okay. You don’t look useless.” She goes back to the panel. “Hold this.” She hands you a piece without much explanation . Trust her—or simply don’t have time not to trust her. “If this fails, we lose energy… and probably worse.” A short pause. Lower , almost to herself:
"But it has to work."
"So... are you just going to stand there or are you going to help?"
