If Passepartout arrives from Belém on Captain Rossignol's Airship he will immediately be brought to Signare Rossignol upon reaching Dakar. She accuses him of being a French spy and enlists his help in beginning a revolution. Whether he agrees to help or not, she attacks him with slow-acting poison and forces him to deliver a parcel to an associate in Timbuktu named Jeanne-Marie. All other routes close until Passepartout delivers the parcel.
However, if Passepartout befriended a rubber tapper in Tabatinga and agreed to deliver a Vial of Tree-Frog Poison to a "friend" in Dakar, Passepartout may deliver it to Rossignol, who is very grateful and lets him go without further hassle.
