Tommy Ritz 6th Canto XXII

In canto XXII the poets set off for the 2nd bridge, since the 1st one lay shattered, leaving the second bridge as their only way to the 6th Bolgia. As Dante walks by the tormented sinners he notices how they behave like frogs in a way. This is because when no one is near they leave their heads out of the burning pitch, but whenever a demon draws close they immediately put their heads under the pitch to evade the demon’s wrath. As the poets and their demonic guardians walk by Dante notices an unidentified Navarrese who tries to submerge too late, and is caught by the demons. However before the demons can set upon the Navarrese, Dante asks the demons if he may speak to him. The sinner speaks of how his service to the king and queen of Navarrese forced him to start grafting, which is why he resides in hell. After this brisk conversation, the demons prepare to set upon the sinner; however he tries to cut a deal with the malicious demons. He says if the demons let him go free that he would whistle which would draw all the sinners hiding nearby beneath the pitch to him, whom the demons could then attack. Though suspicious of his plan, the demons agree and as soon as they let the sinner go he jumps into the pitch and escapes. The demons become enraged over this, and two demons even jump into the boiling pitch after him. When they hit the burning pitch, it finally dawns on them that the Navarrese is long gone, so they begin to fight each other. The other demons begin to organize a rescue party to get their brethren to safety. During the chaos, the poets slip away.

1. Why did the unidentified Navarrese tell his story to Dante?
2. Why did the poets slip away while the rest of the demons were distracted?
