Kitty stared ahead unseeingly, unable to believe what she had just heard. 'Maybe another week. Maybe another week. Maybe another week…' The words were like a chant inside her head. She started walking, trying to get away from them – and almost ran into Kurt!

"Kitty! Können Sie mir helfen? Ich muß hinausgehen, aber die Wände halten zu bewegen und die Türen, Plätze geändert zu haben… [translation: Kitty! Can you help me? I have to get out, but the walls keep moving and the doors have changed places…]" Kurt said, trailing off into muttered phrases. Kitty blinked. Kurt looked as though he couldn't stand up without leaning against the walls, and he seemed to have forgotten that she didn't understand German. But he seemed to be – well, if she didn't know better, she'd have said he was happy!

"Okay, well… Help, he definitely meant that, and there was a bit that sounded like 'I must', and – Wanda? And something about plates and maybe… Oh, this is, like, impossible to understand!" Kitty cried in exasperation, throwing her hands up. Kurt watched her uncertainly.

"Ich. Muß. Gehen Sie. Aus. [translation: I. Must. Go. Out.]" Kurt said slowly, trying to get her to understand.

"I… must… something something? Oh, just forget it! Come on, Kurt, I'll get you back to the, you know, infirmary." Kitty took Kurt's arm, and guided him through the mansion back to the infirmary. He followed her willingly enough, even when she led him back to the bed that he had just left. He yawned, and crawled into it.

"Gute Idee. Ich bin und möglicherweise nach einem Rest müde... [translation: Good idea. I am tired, and maybe after a rest…]" he muttered, already half-asleep. Kitty smiled faintly at him, before turning to leave.

"So, ya learnt whut's up with Kurt," Rogue commented, leaning against the doorframe. Kitty started, then frowned at her.

"Yeah. No thanks to you! You could have, like, told me, you know!"

"We didn't think you'd listen," Evan admitted sheepishly. Kitty was about to retort that of course she would have, when she suddenly remembered the way she'd behaved at breakfast. Her cheeks flushed with shame, and she looked back at Kurt as if he would be able to hear her guilty thoughts. He stirred for a moment, but didn't wake up. She shook her head clear, and then turned back to Rogue and Evan.

"You guys know that he's, like, delirious, right?" she asked softly. They both nodded, watching her curiously. "Because, you know, he was just wandering around the halls when I found him. I think that Scott was meant to be keeping watch, but he got his shades knocked off –"

"How d' ya know that?" interrupted Rogue.

"Because I, like, heard Scott tell Logan to take his watches!" Kitty hissed, "And that's the reason he gave." Rogue didn't look convinced, but nodded anyway. "So if the grown-ups can't, like, keep track of Kurt, maybe we should try to instead!" Kitty finished triumphantly. Rogue and Evan exchanged glances.

"She's got a point," Evan remarked. "Someone should keep an eye out for Kurt, and if the older ones can't…"

"Yeah, you're ra'ht," Rogue agreed. "So, how're we gonna arrange it? Kitty and me for if he goes walk-about, Evan for if he gets too active?"

"Sounds good to me," Evan grinned. Kitty nodded enthusiastically. Rogue shrugged.

"So we got it all planned out."

While they sorted out the fine details, Jean ran through yet another test on Kurt's body chemistry. 'With any luck, this should help us find out what's wrong with Kurt, and how we can cure it," she thought hopefully.

She stared at the results. She reread them. She stared again. Finally, she leaned back in her chair, and thought to the professor, This problem with Kurt might be more serious then we realised. You see, according to these tests, the changes that helped to save his life – weren't natural.

What are you saying, Jean? asked the professor anxiously.

I'm not sure how, but his body chemistry has been altered by someone to help him survive the poison. It seems to have been done several years ago, which is why I originally thought that the changes were natural. His body must have been fighting these changes for years – and now it's succeeding, and killing him. And if we can't find whoever did the original alterations, to tell us how – Then Kurt will die from being poisoned years ago, the professor realised.
