This ambush at an MCR concert is an assassination attempt by Voldemort to murder both Ebony and Draco. There seems to be two instances in which Voldemort executes this particular plan, but only the second gets a proper conclusion.
History[]
Prelude[]
Voldemort loses all patience with Ebony and her unwillingness to participate in his evil plan to kill Vampire. Therefore, decides to follow up on his threat to kill Draco and also Ebony herself for good measure. Voldemort and his Death Deelers disguise themselves as Gerard Way and MCR to ambush the goffik vampire when she least expects it.
The ambush[]
When Ebony and her friends are enjoying the concert, Voldemort decides to drop his disguise by pulling off his mask, followed by his Death Deelers doing the same. For some reason, Ebony and Draco do not flee the scene, but instead stay where they are. Vlodemort starts to berate Ebony for not obeying him. As a punishment, he will kill both of them. He unsheathes his knife (despite being able to cast spells with a wand) and intends to follow up on his threat.
However, a goffik Albert Dumblydore appears at the site and is equipped with a long black bread. He shoots a spell at Vlodemort, who immediately flees the scene. There is no mention what the other Death Deelers do.
Aftermath[]
After this ambush, Dumblydore permanently becomes goffik. However, his attempts to befriend Ebony and the other goffs are met with absolute disgust, being derided as a poser.
