Sheyan remarked ruthlessly, "Your approach is simply running away, professor. Even if the integration fails, it's still a better option than to let history run its course! If we don't change history, Jean will be seriously injured in less than a week and she'll be swallowed up by her alternate personality. When that happens, not only will we lose Jean and Scott, we'll also have a new enemy in the Dark Phoenix, a powerful Class 5 mutant! But if we do as I plan, even in the worst case scenario, Scott will still be alive and we won't have to face a powerful enemy like the Dark Phoenix!"
Professor X was silent for a long time. He then said, "None of us can decide the lives of others. If we preserve the status quo, the situation you say may not necessarily come to pass as long as we protect Jean carefully. As long as the main personality is not severely injured, my mental cage can last for at least a hundred years."
