Were they supposed to have been romantically involved? Maybe it was bad translation (I've recently watched the ADV version, still didn't seem like they were more then just friends at that point - but I don't know of female friends that clean up the house...)
Thanks!
PS - I'd put DYRL as my favorite, strictly for the scene where Hikaru chooses Misa after Minmey runs off (he was obviously about to tell Minmey that when Misa walked in). The reason is the emotion Misa's Voice Actress put into it - she really sounded like someone trying to hold it all together, but just couldn't...
(but the movie needs the TV series as a reference or it just doesn't fill in enough details)
