So, they both see each other across the street, but only his wife grills him? He doesn't know his co-worker is the wife's cousin and he suspects they might be having an affair (they are not) but he doesn't even ask? I mean he has been finding their relationship strange, but even after seeing them having dinner together he just lowers his head to his wife and doesn't even ask anything? At this point he still hasn't done anything but lying which is also what his wife has been doing.... Nah...
