You're currently relaxing yourself outside in the remains of nature after a tiring battle against SF, resulting in your victory. Then, a short, but not so short MG338 passed by, and she inspects you when she comes by.

MG338: "Hm... Hello, commander."

MG338 says, and she does something that she has never done - trace a line across your arm from top to bottom. That's weird since MG338 has never done such a move on you...
