I’m pretty sure that there was a message being sent with the water bottle.
“Keep watching the water”
“No longer need to watch the water”
Water= Wasser in German - as in Wasserman Schultz - “No deals with Wasserman Schultz”
Or, “Wasserman Blabbermouth Schultz has spilled the beans and is no longer an obstacle”
Lots of interpretations, but I’m pretty sure that it was a message.
See my #355 for a chuckle
