Grantaire is asleep throughout most of the conflict in the barricade, only waking up once the National Guard has cornered Enjolras.
Grantaire is seen taking part in the earlier attacks.
Once Javert is freed by Valjean, he returns to the streets and does not revisit the barricade.
Javert returns to the Rue de la Chanvrerie once the barricade has been captured, giving a medal to the dead Gavroche and seeing Valjean disappear into the sewers.
Valjean encounters Thénardier at the end of his trek through the sewers, where the latter offers to open the way out in exchange for the money in Marius's pockets.
Thénardier finds Valjean at the point where the latter fell into the sewers, and only tells him which way the exit is.
Thénardier cuts a strip of cloth from the unconscious Marius's coat.
Thénardier takes a ring from Marius's hand.
Javert happens to be situated outside the sewers when Valjean emerges, having tailed Thénardier to that point earlier, and does not initially recognise him.
Javert is outside the sewers expressly waiting for Valjean when the latter emerges, recognising him immediately.
