Kendrix: It's all or nothing now, and he knows it. Now he's really under pressure, after all, he doesn't want a person he only just met to get hurt because of his personal shortcommings, and this proves to be an useful incentive to get Shinji to do something. (previously seen in ep 3.) Of course, this is subverted later in ep 18 where his wish not to hurt anyone PREVENTS him from fighthing.
