Okay, back from vacation -- sorry if I've lost track of the comment threads (this site is much better populated than when I started posting a year and a half ago -- hard to keep up). In case nobody's pointed it out...
KALDUR IS THE MOLE!
Okay, LAST season I was wrong about Kaldur being the mole. THIS season I'm right -- you'll notice he didn't actually do anything evil in that episode -- and even warned the League about their danger in time for them all to get out.
So you see, I was right! He is the mole... just not a mole in THE TEAM. (Okay and he's not a clone)
