Tarn wasn't having a very fantastic day. I mean like, the DJD were no longer murders as per Megatron's command and the lack of Decepticons left. Ah yes, Animated, where everything is fucked.

The DJD were stuck reporting to Megatron when everything went to shit.
"Looks like Tarn still has his Megatron kink," Blitzwing said to Lugnut.
"WHAT," Tarn said, punching Blitzwing in the face, before being hit by Lugnut's P.O.K.E (Punch of Kill Everything) into a wall, being knocked out.

Vos spoke his first words that weren't Old Cybertronian that day.
"Tarn is fragging dead."
