Re: Astonishing X-Men - series discussion (spoilers)
Ya see, funny story, they let Austen write the last two issues of New X-Men (#155 & #156), ergo they don't count.
thee great one said:"Planet X" hinted and "Here Comes Tomorrow" directly implied that Nova had taken the form of the young mutant Ernst. In New X-Men #156, Cyclops and Beast investigate Cassandra's prison following the destruction of the mansion to find it empty. Fan speculation points at Martha Johansson, a telepath, as being responsible for at erasing the memory of Cassandra and the existence of Ernst.
Cassandra, back in her original form, returned in the "Danger" storyarc of Astonishing X-Men, alongside Sebastian Shaw of the Hellfire Club.
