Thank you for showing that scan of her borrowing power from Rachel without harming her. The control she got in Excalibur was even better than the control she mastered her the Gambit and Rogue book.
Back to Synch it would be interesting if he and Rogue had to use their powers together somehow. Like if he had to Synch to her powers, including her ionic powers, and if she borrowed his synching for some major battle.
