Marcelle and Pelo are still marked and grieving of the loss of the child they were supposed to have ten years later. Louis runs away as the stress become to much, seeking refuge on the rooftop of a church. He is later found and taken back by his mother, after she has given birth. Louis then goes back, helping and saving Marcelle and Pelo’s relationship.
