I'm not reading that big spoiler!
I have a good idea who it is though... I think...
Loved ep 23... some shocking moments to be sure. This season has 26 episodes right... we must be on the doorstep of the next city... cant's wait. LOVED the snow ball fight and the fact Tao had never seen snow before. The "padd" they found seems to show the next location of the next city of gold in Japan.... I just hope this city survived being found.
Ep 22 and 23 also had some great musical moments which has been somewhat lacking compared to the 1st season from the 80's. Moments when they are traveling and it just silent are too noticeable, here's hoping they keep up the music aspect of the show.
