Ron Weasley - Rose Weasley - James Sirius.
He was sinking away into thoughts and memories of a perfectly cut field of grass that spread out into the most glorious Quidditch pitch a person may have very well ever seen. The corner of Ron's mouth began to turn up as Rose, unknown to him, crept into the apartment and began to sneak up on him. It wasn't until she spoke that Ron's blue eyes snapped open and he sat up quickly, scrambling out to reach for his wand. Half a second later, once he realized that he wasn't under attack, Ron pulled his hand from his pocket and shot Rose and - as he approached - James a glare.
Cursing, Ron rubbed at his eyes and muttered, "Want a bit of advice? Don't sneak up on a man at war." Or a man who was mentally still at war. The last place he had been in their world was in the middle of Voldemorts rise. Not a pretty place to be. "You might lose an eye or an ear or - what d'you want? Who are y..."
Wait a second. The ginger one had been talking about mothers and the other one looked too much like -
"Oh, you've got to be bloody well kidding me. Really. If I'd have known that you two were going to turn up here..." He'd have, what, run away? Not shown? Maybe. Hands dropping back to his sides, Ron glanced between the both of them and arched a brow. "Rose, yeah? And...er, James."
