The shrug makes him go tense, but again its brushed away. He finds himself blurting, "But why!?" Just because he can't think of anything as bad as death doesn't mean there is none.

It doesn't occur to him that Sigma could simply lie if that were the case.

There's still a question to answer though, one he nearly cut off. "Had a feeling, I did..." He mutters, looking down. Before remembering himself and pulling his eyes back up. Pay attention for quick movement.
