[It sounds like someone has just run a marathon with the way he's breathing over there, although that eventually slows down to deeper, calmer breaths. There are a few moments of near absolute silence from his end until a pained sigh can be heard. A groan and a thump, presumably the sound of one sitting down heavily. The voice that follows is a bit high pitched, well used, and is very obviously British. A Cockney accent is evident.]

A-Ah dunno where Ah em, an' me 'ead is killin me summfink 'orrible.

[A pause. He begins to babble to himself, almost incoherently at first, before he calms down again.]

Inna prisin, yea? Wiff whales! Terrible whales they is. Do'phins is jus as bad! 'orrible, 'orrible do'phins...

[Another pause. When his voice returns, it is low and hoarse.]

Muds? If yer out 'ere...

[Nothing else can be heard. There is complete silence on the other end.]
