I agree with you. No wonder JA gave them a dirty look when she found out she was being talked about, with her in the house! I think Chris and Sky were trying to "guard" TA's chastity, or something. I wonder if TA stood up and defended JA's honor and left their home. TA was 30 yrs old not an underage boy. Bad form for CH and his wife to talk trash about JA while she was in their home.
With all due respect, we don't know exactly why they talked trash about Jodi. I can't remember the original interview, but there was something that upset them. Furthermore, they were Travis's long time friends, I presume they were looking out for Travis, they didn't know Jodi very well, she was not their friend.
As it happens, they were quite right to have their reservations about her, given what has happened.
I don't know if they were inappropriate with Travis or not, but I am not going to criticise them for looking out for their friend in their own home, when we don't fully know the circumstances.
