Dr. Arada, who is what her marital partner Overse calls a "terminal optimist," was somewhere in the comfortable middle zone. Dr. Thiago was firmly in the "Let’s investigate the dark cave without that pesky SecUnit" group. Which was why Arada was pressed against the wall next to the hatch to the open observation deck with her palms sweating on the stock of a projectile weapon and Thiago was standing out on said observation deck, trying to reason with a potential target. (That’s "potential" per the earlier conversation where Dr. Arada said Oh SecUnit, I wish you wouldn’t call people "targets" and Thiago had given me the look that usually means It just wants an excuse to kill someone .)
