Question about the ending (Spoilers)
Having just caught up on Transformers Prime (I'm a G1 original fan by the way). But at the end of this short tv movie, why didn't Optimus just take the Matrix of Leadership out of his chest and use it that way? This way he wouldn't have needed to die.
The first time he used it on Transformers Prime was against Unicron, he didn't take it out then either. This is confusing to me as in the past Transformers incarnations it was able to be taken out and used without the previous owner having to die.
