A serious man who’s attention is immediately engaged with words like ‘fugitive’, ‘stowaway’, ‘smuggling’ and the suggestion it might have happened at his spaceport. 

For this Legionnaire, the word ‘idea’ is something of a foreign concept.  Give him a recipe and he’ll follow it precisely and to the letter and die trying to finish his cake, ask him what to substitute for flavouring and he’ll look at you blankly and then berate you for failing to follow proper procedures.
