@xts
yep i would also bet on it that he knows or deeply suspects that she is the woman he slept with
but i would also say he has no clue that she is pregnant as a result of it
because even exposing a pregnant woman to smells she gets nauseous from is more or less torture and his smile and bearing look to me like he wants to do a good deed while also teasing the hell out of her
little does he know its going to backfire well at least based on my observations on pregnany women near food they are adverse to
edit: if im wrong about his intentions then he is a super sadist because thats the smile and bearing of someone that sees or expects to see something he is fond of
