Here Chief, have your not-sister walking up. Firstly fact to notice would be, she's in a bikini. Second fact to notice would be that she seems very bemused by this whole situation. She's just sort of wandering along the beach until she spots him.

Next instant, here. Have two big, scarred up Spartans just chillin'. Kelly's not so much big as she is tall, but, you get the picture.

She nods to her C.O. "Sir."
