Watch the water refers to the painting in the background in NK. The painting changed from a storm to a beautiful sunrise and this was pointed out by an anon to symbolize that Kim Jong Un was liberated from deep state. Q acknowledged this in post 849:
First picture from NK: https://qanon.pub/#744, https://qanon.pub/#745
Second picture: https://qanon.pub/#846
Final post with anon showing both pictures, where the background has has changed: https://qanon.pub/#849
That was an anon posting that question, which Q replied to with the image. I don't know the context of the question, because that was posted on the now defunct 8kun board. I believe the first image depicts President Clinton. The point of Q was to show that the painting has since been replaced.
