But when Lupin starts transfering Hermione said:-
"Oh my- He didnt take his potion tonight! He's not safe"
Snape says "I came to bring the potion to you Lupin, as you havent taken this week, but you werent in your room." or sth like that. So we know he hasnt taken the potion, and it must be taken in the week at any time before moon gets out.
