You stay good friends after his/her confession. One night though, you are awoken by a persistent noise as if someone was dragging his feet to-and-fro in the corridor opposite your cabin.

You pull the corner of your window curtain slightly apart and see the cook dragging a heavy plastic bag to his own room.

What are you going to do?

    Think it is none of your business and go back to sleep.
    Open the door and ask what he's doing with that bag.
    Tell the rest of the crew.
