In the notes sent to Burrows, if you read the last word of every line, it reads: "It's LJ, I'm with Veronica I'm okay. I love you."
T-Bag: (about Tweener) Boy's a bit confused about his pigmentation, but he sure does have spunk.
Michael: (to T-Bag) If you wan't to sing, then sing.
Veronica: (in text message to LJ) Dump the phone, they're tracking you. We're in New Glarus.
Michael: The man you're talking about died the moment I stepped inside these walls.
Mrs. Steadman: If we talked about who had motive to kill Terrence, we'd be here all day.
Veronica: I'm sorry?
Mrs. Steadman: Look around. Half the people in this place were shareholders in his company.
When we first see Tweener in the yard, we see that one sleeve is rolled up to show off his tattoo. If you look at this tattoo closely you can notice it says "LG." This is the initials of the actual actor who plays Tweener - Lane Garrison.
