Before we get started here, I'd just like to clarify a few things.
Italicized paragraphs (as in chapter 3 – I think?) were Rose's memories, sometimes Scorpius's. So, when Rose is sitting by the fire, that actually happened; when Scorpius's memories come along, that happened as well.

"Up," Lily commands, softly but insistently.
Rose props herself up on her elbows, the dark shadows under her eyes even more prominent in the thin, straining sunlight. She blinks away the nightmares behind her eyelids, basking in the warmth. "It's Saturday," she mumbles, yawning.
"Exactly. Dress shopping. I owled your mum, she knows a few good Muggle stores we can find dresses at. Muggle prom or whatever, it's in five days. We're running out of time!"
Rose can't help but smile at Lily's enthusiasm, feeling herself begin to lighten up. She watches Lily fondly, as the latter rolls out of bed, drawing the curtains in the corner. Fiery red hair – both of them. Cousins in blood, she can't help thinking, but sisters at heart.
Rose runs her fingers through her wet hair, wrapping a towel around her front. She can hear Lily's voice through the door, talking, as she pads, barefoot, out of the bathroom. Assuming it's Ashley (Brown, their other roommate), she walks out behind Lily.
And standing right in front of her – Cousin James. His eyebrows disappear into his messy dark hair, and Rose blushes, pulling the towel tighter around her. Definitely. Not. Ashley.
"James!" Rose grins, conversationally – though a bit louder than she would have in normal circumstance, though, admittedly, desperately overlooking that she's standing, we and naked in front of him with a towel wrapped around her.
"Rose, Rose – it's been too long. I think we're having you around for the Christmas holidays, we'll catch up at a better time then…"
Rose nods, splattering the rug with little drops of water, from her hair. Lily stands between them, nodding as well, though slightly sarcastically.
"Well James," she sighs, "You'll have to excuse us. See you later, big brother." James raises his hand to his brow, pretending to tip a hat.
"Same to you, Lils. See you two at breakfast." And the door shuts.
"Thank God for puberty," Lily sighs, chancing a look at Rose, who's managed to…change into somewhat more decent clothes. "The James a few years ago would never have let you live that down…"
