A/N: This is part of a longer fic I'd eventually like to write. Basically, John and Elizabeth were shot with some kind of toy McKay was playing with, and they've been jumping around alternate realities ever since.
He knew she was there without even opening his eyes. Her body was warm and pressed up against him, his arms wrapped around her tightly. His nose buried in her hair, he breathed her in deeply, letting himself relax.
Jumping from dimension to dimension - realities, McKay would call them – was seriously screwing with his head. He wasn't sure if they'd been gone for days or months, or where they would end up next. At least Elizabeth was stuck jumping with him – sometimes her presence was the only thing holding him together.
And she was his, in this world. They'd been lovers, friends, strangers, and everything in between. Each reality gave them a different story, and some were easier to bear than others.
He knew they'd have to get up soon and figure out where they were this time. But he was warm, and he was comfortable. Elizabeth was his – for the time being, at least – and he wasn't quite ready to let that go. He wouldn't admit it out loud, but the realities where they were together were his favorites.
Burying his face in her neck once more, he held her tighter and drifted back to sleep.
