The orc again twists away, realization coming to its eyes as the blindness wears off. He doesn't cooperate. Eusebius grabs him. The orc fails to break his grip, but removing the gauntlett will be very difficult while the orc is struggling and kicking.
(For some reason I thought Brother E was grappling the Orc. If not, he's not flat footed, but Banion probably gets a +2 flanking bonus on his attacks.)
