Tarn looks between Rodimus and Megatron, clutching his injured hand close to his chest. He considers going back and finishing the job with Rodimus, but he doesn't trust that the Autobot won't play up his fire trick again. So he goes with the other ill advised option and starts stalking toward Megatron.

He ignores the multiple weapons aimed at him and moves in a slow but purposeful way, trained solely on his old Commander. He stops a few paces away locking eyes with the pistol aimed at him.

"You have made a mistake, Megatron." he growls, curling his injured hand into a fist, ignoring the sharp sting. "You have betrayed the cause, those loyal Decepticons who have sacrificed their lives in your name, your followers. You have betrayed me."

Tarn bows his head just slightly. "I will mourn the mech you once were but I can not allow this egregious failure to go unpunished. It is my duty. I will not fail as you have."
