It does exist. They’re very similar to one another, but the difference is that third person deep takes it a step further. For example:
In third person limited, you may say:
Jamie shook his head. This idiot doesn’t know how to talk to women, he thought.
Tom’s mouth opened, about to say something, but instead gave a small, nervous laugh.
Wow, that’s attractive.
In third person deep, you may say:
Jamie shook his head. This idiot didn’t know how to talk to women.
Tom’s mouth opened, about to say something. But the loser gave a small, nervous laugh instead.
Ha. Moron. That wasn’t attractive at all.
I do. I write in both third person limited and first person.
Honestly, not that hard. First person and third person limited are basically the same, just with different pronouns.
No, and I never will. Omniscient is a very, very difficult perspective to master and nail down perfectly. I will not try it. xD
