How does it work?

"Do you understand now, Alice?" Sam asked, a sinister smile on his face.

Alice was froze in her place, unable to say anything. After a few seconds she lowered her head in defeat, her shoulders trembling slightly. 

Having won the discussion Sam let out a sigh. He looked at the two Valkyries in his arms the gave them some instructions.

"Alright, it's time for you three to leave." He said. "I need to talk with the commander."

"Are you sure, Doctor?" Nine asked, her eyes full of worry, and so were Five's.

"It's okay. There is nothing to worry about."

Glancing in Alice's direction for a moment, Sam went on to kiss Nine then Five. He then turned to the young Valkyrie who was blushing to the ears having seen everything. He gently patted her on the head, smiling at how adorable she is, then backed away a few steps. 

"I will be waiting outside. Please call me if you need something."
