Marius is surprised to suddenly see Leblanc and Ursula again. Where do you think they went after they moved from the Rue de l’Ouest? What were they doing? Write as much as you can.
I have confidence in the reason why Leblanc and Ursula moved out. I believe it is because of Marius. They would have moved to a place where it isn't too far from the church, but where it is far from the Gorbeau house, where Marius lived. plus, they might have moved near another park. Since Jondrette family knows Leblanc as 'generous man from the church', they must have been helping the poor. And they will likely continue going to the church and the park.
