I was re-watching the Hobbit when Bilbo was writing to Frodo that nothing unexpected ever happens to him. (queue Gandalf). That mirrors the reference John Watson makes when we first see him in ASiP.
I've been away for a bit so I'm not sure where this topic should go, but has anyone else every observed important lines for different characters that are so similar and also played by the same actor?
