Days later (on 8 July), Laura's attractive older step-sister Claire arrives. Upon seeing Claire's knee while she is on a ladder, Jérôme finds himself longing to touch it. However, he controls his temptation. Eventually an opportunity presents itself during a boat trip on the lake when Jérôme and Claire have to seek shelter in a hut from an approaching storm. Jérôme tells Claire that he saw her boyfriend, Gilles, together with another girl. When Claire starts to cry Jérôme consoles her by placing his hand upon Claire's knee.
