I don't know what I think about the CDs. I want to say if you're packing, why would you pack these CDs, just as JM pointed out. Others have mentioned that they have things in their bags that just stay with them all the time because they never clean their bags out.
But, I do kind of believe it's a stretch that she moved away, packed her stuff, unpacked her stuff and set up a new life in Yreka, and these CDs of her old life with Travis somehow stayed in her bag that she carries with her all the time. The idea that the CDs got in her bag in the first place is in question for me. Who made the CD and where? If she made it at home, which I assume because she's a "photographer" and probably has software, why was it in her bag? who was she going to show it to or where was she taking it that it would just "be in her bag" incidentally?
I assume this was a trip she took with Travis before she moved. When was this trip? How is it that Travis didn't get copies or didn't see this CD before she moved? Could it be because the CD hadn't been made yet and she made the CD while she was in Yreka with the plan of giving it to him when he visited? Then when there was no hope of him visiting, she did put it in her bag to take on her deadly trip? Maybe to "remind" him of their good times on trips so she could talk him into letting her go to cancun? I'm not saying take Mimi's ticket. I'm saying BUY Jodi her own ticket.
Could it be that Travis actually did throw that CD against the wall because he knew it was a ploy?
