Ienzo's surprise was rather more obvious than Marluxia's.

Even was a coward. He was fully able to win a fight when it came to combative magic, but he was a coward and, for as long as he'd known him, he seldom put himself in a position where he fought if he didn't have to. Did he have to? Could they win without him?

His analysis of the battle said no. He was concerned about their ability to win even with him. Not all of the Arrancar had taken advantage of their powered up forms, so they had that to fall back on, and Lumi and Marluxia were both obscenely powerful, if he reckoned correctly. Gin also hadn't lifted a finger.

They could win, they could probably win, but they would have to wear the monster down, and how long could that take?
