While discussing the coded message, Eric says that it's a simple cypher, but that the victim ran it through multiple different keys. That makes no sense. Running a message through simple cyphers is ultimately no different from running it through one. For example, if your first key were d=a, o=b, and g=c, and your second key were a=1, b=2, c=3, the word "dog" would be written as "123", and it would be true that d=1, o=2, g=3. Eric must mean something else, but Callen and Sam clearly understand it to be series of simple cyphers. If that were the case, Eric should be able to decode the message in no time using a simple computer algorithm. See more
