Trevor was a Visitor and a member of the Fifth Column living on the Sydney Mothership. Unaffected by Anna's Bliss, Trevor feared Anna's Bliss was stealing his girlfriend, Mia, from him. Failing to break Anna's hold on Mia during another Bliss session, a depressed Trevor, vowing Anna would not have Mia under her control any longer, calmly took out a Blue energy grenade and armed it in a group of Visitors who were experiencing Bliss. The grenade detonated and killed Trevor, Mia and all others around him. His last words, to Mia, were a testament to the emotional commitment of the Fifth Column - experiencing emotion, Trevor's last words, to Mia, were that he loves her.
