Rebecca was pacing in her office. At the moment she was working on the scar and the philosophers stone case. Rebecca was just in her tank top and her military pants(showing her automail) as she stared out the window, waiting. With a sigh she stared out the window. "Damn..." Rebecca has four automail parts, and no one knows.
If in the military:
You went to General Rebecca Mustang office. You saw her pacing around and you saw automail! With that you went to Roy Mustang but stop.
Do you tell or not?

Working with lust?:
You and lust where waiting for the right time to strike. As you watched the young General both you and lust saw her automail. With that you attacked.
You had the female trap while lust went through her work. "Do what you want..." Lust mumbled as she picked up something.
What do you do....

If anything/anyone else:
