I've been working on my novel for a bit, and recently hit a landmark section in which I introduce two new characters that are going to become very central to the continuing plot. When I started this story a while ago, it was designed as another part of a series of short stories I had done over the years. I added this one character; (a hyper intelligent lion that's the result of a highly classified gov't project.) (Don't ask, it's complicated. ) He sounded great I thought. When I decided to expand the entire short story into a novel, I started out from the beginning. It's all written in 1st person, mostly from the MC's perspective. In order to advance the plot and show the reader some of the other things going on outside of the MC's POV I occasionally change who the "narrator" is for a given section. The problem I have is now, a year after introducing the new character, I've come to a part where I need to narrate from his POV, And he sounds choppy. By "Choppy" I mean he sounds like his dialogue was forced out and doesn't flow smoothly with the rest of the characters. I'm trying to figure out how to find his "voice," how he sounds in the dialogue. (Since it's essentially all dialogue. Are there any methods for making a character sound more natural and not like I pulled his dialogue out of my head with a toilet plunger? I hate to say it, but I'm not entirely sure what kind of help I'm asking for, but this has me stalled on my work, and it's frustrating.
