 At the end of "Half-Life 2", the G-Man emphasizes the word "time" repeatedly as well, most likely referring to the fact that moments before, he seemingly stopped time.It is common for the G-Man to elongate "S" sounds.His odd manner of speaking, along with his appearance, alludes to the behavior of the "men in black" in various reports, and the apparent age and physical status of the G-Man does not seem to change in the time that passes between "Half-Life" and "Half-Life 2" (which, according to the "Episode One" website, is nearly twenty years).
