Inspired by McKay and Mrs Miller. I googled the meanings of the name 'Meredith' and basically it meant 'protector from the sea', and it kinda inspired this. Many thanks to Scribewraith for beta!
From The Sea
When Rodney McKay signed up for the Atlantis mission, he knew it was possible that it was a one-way trip. What he hadn't counted on was how short a trip it would be: for all of them.
"Just lock yourselves in and go!"
Who would have thought that his last act would be one of self-sacrifice? Rodney never even knew he had it in him.
The water was rising fast and Rodney hadn't heard anything from Weir or from the Air Force Major. Within moments, he was up to his waist in freezing alien seawater. The controls behind him shorted out and his laptop screen went blank as Atlantis' system failed. Rodney could only hope that they had somehow managed to escape.
After one last futile attempt at getting the computer to work Rodney tossed the useless piece of machinery, watching as it sunk to the floor. He should be panicking, swallowed up by fear, but all he felt was an unexpected sense of calmness. A part of him seemed to recognise that this was where he belonged.
Rodney opened his eyes one last time under the water. The blue-green hue of the flooded city was mesmerising.
He was finally home.
