Arnold was pacing back and forth at the place while Talos and Natasha patiently waited for him to say something. He had called them there and yet, he was lost in his thoughts. Although Talos wasn't an expert when it came to human emotions, even he could feel that something was off with his master.
He knew the situation was bad when even warmongers like Asterios, Grock and Bad-Breath were not being their usual selves. Even Dread realised something was seriously wrong when he saw their usually fearless master sweating buckets while shaking uncontrollably at the same time. At first, the summons thought Arnold was seething with rage, that's why he was shaking. But then again, nothing of the sort happened that would've sent him in a fit of rage. Enough rage that he would order them to kill innocents.
