hmm...i just saw DAN and IDAN....never realized it could've been 'guidance'. Atleast that clarifies who the man was.

ok, crazy theory #2. Could fembots appearence be based someone john knew/knows in the future? Im thinking wife/girlfriend. When they went to meet the future soldiers, sarah asked if they'd know who she (fembot) was, and she said "they've seen me before", instead of a simple yes or "ya, they reprogammed me".
