Q's capitalization of PAIN strikes me as the capitalized reference, in gaming terms, is a bit different than the normal usage. I may be looking at this too deeply but a "PAIN walkthrough" is going through a high difficulty setting without taking any damage (at all). I don't know, I am probably wrong on that but the capitalization of the word tells me we may need to look deeper into it. Q has always done things like that to emphasize what we need to consider more than norm.
