Having fun is the key to the puzzle. I just do not know how literal they are and it is a big jump from having difficulty with a four digit code on a key pad to deciphering obscure symbols and complex organics. Did Ink really have enough of his shit together to create Arrow Head from Austin McKibbon and all the complex locks of the jail and then run into difficulty with the four digit code at the Tower?

Another bit of frustration is that are we actually given first and last name of the prisoners held in solitaire with the exception of one -- Cohen. I have to relisten to this. Who the hell is trying to protect Cohen by omitting his proper name from the journal entry that we are now hearing...
