well i also agree, i think there could have (or could still be) some sort of romance going on between the cast members... its kinda weird to think about but maybe .. er i dunno maybe they just cant say anything, even the littlest thing cuz then rumors (even more than this one) will fly and i mean, if they dated (any "they") and then broke up theres just like this rift in their relationships (which is maybe why theres those things about not dating co-stars)..
