In the Lord of the Rings Trilogy, I always believed that Gollum talks to the Ring 'precious' as a person. I was rewatching The Two Towers and I noticed during Frodo and Sam's first encounter with Golum, Gollum is talking like this:
Sam: It’s hopeless! Every Orc in Mordor’s going to hear this racket! Let’s just tie him up and leave him.
Gollum: No! That would kill us! Kill us!
Sam: It’s no more than you deserve!
Frodo: Maybe he does deserve to die, but now that I see him, I do pity him.
Gollum: We be nice to them if they be nice to us. Take it off us. We swears to do what you wants. We swears.
Here, Gollum is talking to himself like another person but not to the ring. Does he have another split personality or multiple personality disorder? So, how many personalities did Gollum have as split personalities? Also, is Smeagol is one of them?
