I don't really think it shoud be the last episode(though that could happen). As many've seen it is hard on both of them, one not being able to tell and the other not knowing the truth (that's part of the drama/comedy I know).
If Ran did find out would she be alone ? (obviously sonoko is a bit of a gossip, and her dad is just a coward sometimes) How would be the best way to do it? Sometimes it seems like she knows, but when conan would get into terrible trouble she writes it off/acts like she doesn't.
Note: I think Ran and her mom have an idea about who Conan could be, and if her dad was a better detective he would already know.. he's been hit with enough darts to figure it out (lol). I would like to see either Ran turned into a child (sonoko is iffy) or Kudo changed back into a teenager. Ai-chan seems to have found a man in one of the 2 male detective boys, plus it's a full time job almost keeping the professor healthy.
