vidian weakness ear

Balling his gloved fist, he pounded Vidian's left ear. The rest of the man might be sheathed with something tough, but Kanan bet that Vidian needed his ears for balance like anyone else. He was right - at least for an instant, the cyborg recoiled. It gave Kanan enough time to grab Vidian violently by what passed for his ear. Whipping the count's head around, Kanan bowled forward, smashing Vidian face-first into a cabinet with a colossal clang.
Like a spring-loaded weapon, Vidian snapped back around. His face was expressionless, but his mechanical voice betrayed excitement. "Now we're to it!"
