If I remember correctly, it was the episode when they were playing Hide and Seek on a ship. The image you've seen is a flashback, where Ran remembered when she was hiding at school and Shinichi was always finding her. That was a great episode...or it was a movie...
That's because she said that in Romanian are not Q, W and Y...which is not true. Ok, maybe it is, because we don't use them very often, but we still have them for some neologisms and other words Oh, and she didn't mention Î either, just Â.
