I've caught on to a fascinating body language "tic" I believe Jodi has. When she's recounting THE worst situations, she'll smile slightly. Once she even gave a tiny chuckle.
I'm not certain of what it really means. I'm thinking these smiles are a sign that she's lying -- but I could be wrong. These could also be signs of earnest nervousness (true stories).
But I suspect this slight-smile-tic has to do with lying. I think this because of some body language material I've read. Experts say the body/face always does some type of "release" sign when a lie is being told. Perhaps Jodi's release is this inappropriate, tiny smile -- minor GLEE?!!
Here's where I've noticed it. Definitely when she's telling how:
-- Bobby choked her, she almost passed out, and he threatened to kill her family. (CHUCKLES!?)
-- Travis refused to kiss her after oral in the car / she felt like a prostitute. (CHUCKLES!?)
And here are a few more times I think she may have smiled inappropriately. (I'll have to watch her testimony again to confirm these):
-- When describing talk-less sex the first time, at the Hughes' home.
-- After the Baptism, when Travis took her anally.
It's hard to find any emotion coming from Jodi other than when telling these stories. NONE of these things are humorous: they're HORRIBLE. So why's she smiling & laughing? ... I suspect it's because she is LYING.
When Jodi tells what she did to Travis, I'll be monitoring for her inappropriate Mona Lisa smile...
