Hi Hisimage! I don't know if this helps any - I didn't see the NG show or hear that part, but the "pin it on me" part is actually from that phone call home when kc kept asking for TL's ph#.... IIRC she was speaking to KC & it was like kc said "They already said they're gonna pin this on me if they don't find her"....
which I actually took to make NO SENSE whatsoever at that time.... I was thinking "pin WHAT if they don't find her"?!!
Then later, TL claimed he got a text mssg from kc's phone [I think AH stated this to LE during her interview & asked them ask TL about it] but anyways the gist was TL allegedly got a text mssg the same day kc was 1st arrested that said something along the lines of "guess who's going to jail for a long time if they don't ever find her [Caylee]...
which was even MORE disturbing.... imo
