some of us have mentioned this in another thread...but rumors are soaring that rachel is killed by the joker... then a pregnancy rumor started going around...so could joker killing rachel, thus killing her and harveys unborn child, be what ultimately sets him off? well of course with the whole acid burned face ....but wouldnt it be interesting to see harvey get scared BEFORE he actually goes crazy and becomes twoface? it would be very sadistic if joker killed a pregnant person. so i dont know if that will happen, but its possibe...then in movie 3 it could be joker vs twoface vs batman...hey it could work... it does seem like this is very possible, esp inthe type of dark film were expecting with numerous deaths. thoughts? OTHER THEORIES?
