Maybe if Brady and Arianna each have half a brain...

they can join together to possess the Salem Brain!  I really thought Brady had the Brain the other day at the police station when Troy was looking at EJ while ratting out Ari.  The light bulb seemed to come on, and he even questioned EJ about why.  I was so excited, "He's got it!  He's got it! He's....Oh, well. That train of thought just derailed!"  He just couldn't put 2 & 2 together!  And then Ari today picking up the phone with Anna on the line.  Maybe if they get together and compare notes they can get out all their fingers and toes and add it all up!
