Ok, I've been a fan of ALIAS from the beginning and have loved it since then. But the one main thing that has confused since S1, is what's up with 47. It started with one of the first eps. when Marshall made a camara and wanted to get it up to 47 pictures b/c it's a prime number. But now the obession has gotten so overwelming....and I really want to know what the big deal is is about 47?
