Gideon's voice (as Amos thinks of it) is both easier and harder for Amos to deal with. On the one hand, being emotionless, it's comfortable. On the other hand, it means Amos has to pay extra attention to Gideon's expression.

"Alex takes his with three. Think he'll start pouring cereal in it next." Amos picks up some extra parts, fixes them in place, pokes and prods, before, "shit, they got cereal on Mars?"
