This one took me 12 re-throughs. See what you think ...
Twilight (pb 411) "My guilt slowly subsided as I looked into her dark eyes."
They're in the hotel room in Phoenix - Alice's eyes are referred to as dark. So let's see, Sunday night was the baseball game, and Monday morning dawn was breaking over northern California, Monday sunset they were checking into the hotel, and Bella wakes up 3 am Tuesday morning, which is when that statement happens. The previous Friday, Alice and Edward ditched the afternoon to go hunt. Now, the focus was definitely on Edward hunting, but wouldn't Alice nibble a bit while he was stuffing himself? So her eyes go dark in less than 4 days?
Well, I guess there's a lot of behind the scenes stuff that we don't see. I will keep hoping for MS to be completed and released.
EDIT a month later, to avoid double posting: Just thought of this, which is maybe an error, what do you think? When Bella wakes in the hospital in Twilight, it's only been about 4 days or so since Edward drank some of her blood (and more than a week since he stuffed himself in Forks, I think). Now, he didn't drink much, but shouldn't his eyes be at least a little reddish?
