Nope, it wasn't a surprise. It was too obvious that this person was going to be the mastermind behind the whole operation. Frankly, I found the first part of the episode boring, wasted minutes of the characters wondering what to do and how to solve the case. The action scenes were the only redeeming feature, but even so, having the villains describe their abilities and plans, giving the protagonists the chance to neutralize them, is BAD writing.
