For Clark, it's rather like finally coming to the surface after being submerged underwater. All those muffled sounds becoming clear and coherent, and he slowly tunes in to what they're saying, that there are people here talking about him, and he knows those voices.

"Ow," he breathes, half-opening his eyes, so tired but needing to see them. To make sure that this nightmare is really over. He doesn't know where he is, or what's going on, but he's not afraid anymore.
