that is out of context. I just said he was surprised by the manner of the attack,and i'm not backtracking on that now.
temper with this:
pg. 133
"he took the precaution of slipping towards his desk, where he would have access to a dozen weapons and traps he had prepared in anticipation of just such a confrontation. "
Clearly expecting a fight.
pg. 134: "In the next instant, Caedus, found himself flying across the cabin towards his observation bubble. Luke had not gestured, had not flinched, had not even shifted his gaze, He had simply grabbed Caedus in the Force and hurled him five meters into his chair."
My only point i'm making is that Caedus had all the warning he needed to be prepared, and was expecting a fight. The fact that luke attacked him in such a way that Caedus was unprepared for is different than acting like Caedus had no idea an attack was coming.
