It makes perfect sense... Throughout the show he's always believed that he can save Clare. But he finally got a reality check from Helen and he realizes how dumb and weak he really was thus leading him into that state of fear.

I don't think he is scared of Clare... He's just shocked to finally realize there's nothing he can do to save Clare. But after a talk with Jeane I guess he gains confidence again and wants to save Clare.
