I need more evidence for rat face to make a decision on if he's Rum or not. The main issue I have with him is that he doesn't do much aside from the convenient timing of coming over all the time, though that does tend to be a pretty common habit of all the other pretenders in this universe (seriously Akai, your acting sucks). I guess if he's not Rum, then his real identity is either just a die-hard Kogoro fan or he's from another government agency who's keeping tabs on the Mouri Agency since they have so much contact with the organization.
Anyway, I haven't really deciphered the mystery much, but I'm guessing this is supposed to be a mystery where you have to figure out who's injury would be the least debilitating for the crime? I guess I'll put a bet on the wheelchair girl, since I suppose that one's easy to fake or get around by using some murder trick and then they'll try to play innocent by saying they can't walk normally.
Also yay for it being back~
