I did a search of it and couldn't find anything so I figured I'd as the community since I'm sure I'll get an answer or at least a damn good theory or two. What's the deal with the chained matrix around the neck of Optimus in the final episode of TF: Animated? Was that THE Matrix of Leadership? Was it an allspark shard that was encased in the familiar matrix design? Was it like a medal, a reward given to Prime for his bravery? I really don't know. I'm all ears and thanks in advance.
