In the meanwhile, Henri bumps into one of his exes in a café which triggers off Henri’s anger; the past wounds have not quite healed yet. He goes for a hookup to try to forget. On his way back home he stumbles on Tony who is gloomy after an unsuccessful attempt to seduce a stranger in a bookstore.
While Joe and Eric make fun of Steph and his supposed virginity, their friend actually goes into action with Yonick, a stranger met on the net. A couple of days later, Steph borrows Joe’s apartment to arrange a better date with Yonick; while leaving, Joe bumps into Yonick which seems to spur some remote memories of a long ago sex party but without details.
