Jack is being chased, towards Malenia, not that his pursuer knows it yet. There's two kinds of sound on display here: Jack's strides are long and loping, a dead sprint on long legs that makes his pumpkin head rattle, his shoes clack on the cobbles.

The other sound is more intermittent; someone or something fairly light, leaping, sprinting, leaping again; they hit the cobbles in a roll each landing, breathing hard through a maniacal "Wahahahaha!" of laughter.

Hrm. Wait, another sound. Jack's bleeding.

A voice, not the spectral one reported as belonging to Jack; human, edging towards a higher pitch, full of malicious glee: "You're only going to die tired, Jack!"
