Unlike Code-L and Code-B, Code-C felt that his position was threatened as time passed by.
If he couldn't awaken his bloodline and became the real sacred guardian, he would have to give up this position, which he would gladly do.
However, if one gave up their bloodline when they weren't yet a legendary beast, they would die. Code-C didn't want that!
Code-C was inwardly jealous of his two friends.
The other two, Code-L and Code-B, already established their force in the beasts hierarchy and became the real sacred guardian.
Even when their 'owner' died, they wouldn't die. They would just return to their sealed form, wait for the new owner to wake them up while they live at the mysterious prairie inside the Sloan Family's mansion.
Uh, well, that prairie was actually a dimension door connected to Primordial Island.
