A couple days later the bottle is found in the middle of the Entrance Hall, shattered to hundreds of pieces with a small piece of parchment laying amongst the shards.
Any who picked up and read the parchment would see that it reads: "You broke my heart." A magically animated sniveling sad face could also be seen on the parchment.
It is assumed at this point that the bottle was cleaned up by Filch, and rumors spread about the school by the students that reported it to Filch.
The posters have been taken down.
