In season 5 finale there is a scene Jane and Lisbon talking and Jane say :
 - You know , have some certain little childhood memory stick with you forever , you know often times you associate with piece of music or song ?
after that Lisbon answers :
-Sure.Song about the cake being left down the rain ? I always see my mother feeding PİGEONS.I dont know why
Do you think this is suspicious ? cuz you know the relation between RJ and Pigeons
