One day in kings landing the Blacks side of the Targaryens payed a little visit due to being invited over for a little "family reunion." Which ended up with a very traumatic event in thus leaving most of the family members frozen watching Vaemond Velaryon's body and upper half of his sliced head on the floor as Daemon spoke.

"he can keep his tongue." before walking out to get fresh air leaving his wife and children there to process what had just happened as the gaurds and servants did aswel.
