Tarn's head immediately whips to the side to glare at Spinister as he opens his traitorous mouth. But, he doesnt have time to scold him before the word 'Prime' leaves Sentinel's lips. Tarn's optics brighten in rage and he stiffens as Sentinel closes the gap between them, ready for a fight.

He stares, incredulous, as Sentinel walks right past to continue his previous task as if nothing had happened. Tarn's hand shoots out to grab the Prime by his forearm, his grip like iron.

"How like a Prime to belittle another so indiscriminately... I'll have you're head you pompous wretch." He tries to drag sentinel closer. If only his vocalizer was intact; how sweet his death would be...

Unless Spinister says something to distract Tarn right now, a fight is going to break out and it's not going to be pretty.
