V's friend disappeared after a trip to Europe

His best friend, a childhood friend went missing after a trip to Europe with his family. What happened was he turned into a Symbi when he was kidnapped, being forced to see his parents die in front of his eyes, when Gretal went to Italy after sensing a level 4 Symbi made by his friend and brother to kill it. He became hateful only when he grew old because it was his long lasting friend and someone who had accepted him for who he is.
