Talk: Kryptonite heart

The word "matrix"

Was it used on the show or is it from the comics? I thought I remembered the word "heart", but I haven't been paying close attention on this one.

I believe it was only referred to as a "heart", but I could be wrong. I really need those Season Nine DVDs soon if nobody else bothers to figure this out... TheVessel 05:32, March 1, 2011 (UTC)
