Not very talkative, he is reasonable, polite, even formal. He is very elegant and charming. It appears that he and Felix share a close friendship, as they constantly are seen together. Demetri is also very loyal to the Volturi and enjoys working under them. This, however, is due to the influence of Chelsea's power. Demetri also seems to be quite a calm character as for his not being upset when Renesmee turns out not to be an immortal child and he simply leaves.
