Episode 6 - S1.E6

Estelle mistrusts Olivier again, especially after her mother is arrested with her kid sister, yet teams up with him. They discover that his family's crest also fits an element of the prophecy. His family are descendants of the Italian papal palace architect, linked to a specific room which contains hidden frescoes depicting the actual prophecy. Julien's mother is just in time to prevent him committing suicide over his denied paternity, but father and uncle show no concern.
