Nightcrawler figured it didn't need to take a rocket scientist to know what was the matter with Rogue, despite the fact that both Mystique and Magneto had no idea why she wasn't fighting her hardest anymore. Nightcrawler saw it plainly every time he mentioned another attack on the X- men.

Rogue was in love with one of their enemies.

He didn't know which one it was yet, but he was able to rule out Beast, Cyclops, and Wolverine out right away due to their looks and Cyclops' annoying nature and relationship with the one simply called Jean Grey.

So which one was it?

After two weeks of his discovery, he finally noticed that every other Saturday, Rogue went off on her own and often snuck back into their headquarters very late at night happy and almost breathless. He put two and two together and he figured out that she was going out with whoever she was in love with.

Which explains why Nightcrawler was prowling in the dark, following his foster sister. His suspicions proved true as she snuck onto the mansion grounds and headed for the woods in the back, looking back constantly. He moved swiftly, swinging from tree to tree as he followed her deeper into the woods.

Finally, she stopped near a small house beside a lake and a dock. A figure stepped out of the house and the two embraced tightly. Nightcrawler narrowed his eyes and slowly started to move in closer, trying to see who it was she was hugging. When he finally saw, he growled very faintly and shook his head a bit.

Rogue was hugging Gambit.

Later that night, (actually the next morning since it was two a.m.), Rogue slowly crept into her room and was about to get into bed and go to sleep when the light turned on.

"Wot the. . ?"

"Guten morgen, mein schwester." Nightcrawler was perched on a chair, his tail moving lazily side to side. He motioned for her to sit and he sighed softly, shaking his head a bit in disappointment.

"I know vhere you vere und who you vere vith." He said softly.

"Ah wasn' wi' any'un." Rogue lied uselessly. Nightcrawler shook his head as he closed his eyes.

"I followed you, Rogue. You vent to zhe voods behind zhe mansion und met Gambit by zhe lake. I saw you!" he said. Rogue sat down on the bed limply, looking at the ground.

"Ar' you goin' tae tell Magneto?" she asked weakly. Nightcrawler shook his head, crossing his arms across his chest.

"Nein, I von't tell anyone." He promised. "Tell me vhy you like him at least." He said. Rogue smiled faintly, shrugging a little.

"You 'aven' talked tae 'im, Nightcrawler." She said. "e's sweet an' really funny when 'e wan's tae be. 'e gave me a gif' tae!" She got up and went to one of her drawers, taking out a small wooden bow from inside one of her shirts.

"Look insoide!" she said handing it to Nightcrawler. When he opened the bow, he found a small crystal swan with jade eyes looking up at him. He sniffed, fingering the swan lightly.

"I suppose he believes he can buy you, ja?" he asked.

"'e does not thin' tha' way an' tha's not wot 'is gif' means!" Rogue snapped, taking the box back angrily. "Why can' you be 'appy fer me?" She regretted the words as soon as she said them when she saw the change in Nightcrawler's face to sadness. He looked away sharply, closing his eyes for a moment.

"I hope you are happy vith him, Rogue." He said softly, standing up to go. Rogue took him gently by the arm and pulled him back into a tight hug.

"Ah'm sorry." Rogue said seriously, looking up at him. "Don' be mad at me." Nightcrawler laughed softly and he hugged her back.

"I could never stay angry vith you, liebe." He said, slowly letting go and stepping back a bit. "But zhere is one zhing you must understand, mein schwester. If Magneto or mutter find out about zhis, you und I vill be in deep trouble vith zhem und zhe others. If you vish to continue zhis relationship; vhich I know you vill, you must be careful und never let anyone else know about it. Understand?" he asked.

"Ah unnerstan'." Rogue nodded, smiling a bit. "Ah won' let any'un know about this except you an' me." Nightcrawler smiled and nodded, heading for his room.

"Make sure you keep it zhat vay!" he said over his shoulder.

And thus, the stage was set for the Brotherhood's downfall.
