Interesting.
I don't think Kara is subject001. Sure she is there, but that's too obvious... red herring anyone?
Either way, interesting to see the dynamic play out.. I doubt with her super-senses it will be long before she puts the S in Clark Kent.
and Cat... well... I'll reserve my judgement on her for the time being, but doesn't it seem a tad suspicious that she rocks back into the Planet with the same computer she walked out with?
Doesn't sound like that life of luxury everyone thinks she's been living to me....
