Oh shut up, I'm not giving up a chance to see those panties. [It just takes him a little while to get his bearings, cursing himself every now and then - he's running on adrenaline so he's not giving himself time to sit and get cold incase it stalls him from continuing. He could call in someone else but - damnit, he's got this. They have other crap to deal with.]

Stay calm, just listen for my voice and look for the light. [Soothing, oddly out of character (or in it,) for him as he tries to keep her calm like he would anyone he's treating for shock and injury. This water and weather's dangerous for more than one reason.
Once the feed clicks silent, he does start yelling her name as he progresses in.]
