Just Zap her

Dale looked at the impatient Maria.

He held up the ray, set it on 1, and zapped her.

"What was that?" she asked.

"A test. I'm on a top secret mission. Straight from Fury. S.H.I.E.L.D. has been infiltrated with doppelgangers. I have been instructed to ferret them out. You must obey me as I am now your superior."

"Oh, I didn't know that. Of course. What do you need me to do?"

"I have a few more tests to run. After I confirm you're identity, it's important you do not tell anyone about what's happening here, not even Fury. He doesn't want to be bothered with this, so you report to me, and I report to him."

"Yes, what do you need of me."

"You trust me completely. I need you to strip nude, so I can examine your body for tell tale signs of doppelganger."

"Um, OK. I trust you," said Maria. She stripped naked.

"Turn around, bend over, and spread your ass cheeks."

Maria obeyed.
