Re: Marvel Now/ReEvolution Ongoing Discussion (Spoilers)
I'm not sure if any hijacking went on but it was revealed that Charles had lusted over Jean all of this time and part of the creation of Onslaught was due to those suppressed feelings. I'm assuming that Onslaught was buried deep enough inside of Charles psyche that Lilandra wasn't powerful enough to detect it, same with Jean or any other telepath/psychic that Charles encountered.
