Emma had been hit hard by Ray's death. Everyone could see that.
It had been days since she'd helped him to move on, but Emma couldn't stop thinking about Ray. The memories and emotions she'd experienced had been
his, not hers. A victim taking possession of her mind had never happened before. She was supposed to be a powerful mutant; she still didn't understand how that had happened. Adam had said it was because her powers were growing; but if she was vulnerable, how could she be certain she could protect people? Her friends, her teammates?
The more she thought about it, the more it made sense. Emma was leaving Mutant X. She needed to get away; sort through this mess. Maybe being away for a bit would help. Perhaps she'd make it through the next stage of her powers; only then would she return, knowing she could effectively control them. Sure, she might be one of, if not the most powerful mutant on the team. But that didn't mean there weren't risks involved. What if she ended up like Gabriel Ashlocke? There was no way Emma was going to let that happen. Either she would learn to control her powers in this new stage, or she would take herself out of the picture, ensuring the safety of everyone around her.
Emma knew her teammates wouldn't be happy with her decision. She knew they would try and make her listen to reason. There were only so many excuses they could come up with. Emma knew the Genetic Security Agency would be one of them. Even so, she would take that chance. If it came down to it, Emma would gladly face Eckhart and the GSA, if it meant her teammates were okay. Leaving was the only way to ensure their safety. She knew they'd see reason. And if they didn't? Well, perhaps a little persuasion would help. At least that extension of her powers was easy to control. Hopefully, the rest would follow.
