yea i suppose they probably would tell him, i mean they dont seem like they wanted to try and hide it when obi-wan asked who they were for. i guess that makes sense. actually....what the hell are we talking about..man im dumb..haha!
in the scene with obi-wan and jango obi-wan says "your clones are very impressive" and jango says "they'll do thier job well"
so obviously he knows, lo,, i suppose you can close this thread now. unless we just talk about random clone army stuff etc.
