She paced back and forth, holding the diary to her chest. She didn't trust putting it down, not after the letter vanished. Maybe - if she put it down even for a moment.
She couldn't help but think it would vanish as surely as Vaughn did when he slipped through her fingers.
She didn't have any proof of it - that it would degrade so quickly, But she just couldn't risk it. She couldn't be responsible for it with a stupid, reckless choice like that.
Actually, there was no reason to believe she could just stop it from vanishing if she held it.
There was no reason to think, just because she remembered Vaughn herself, her holding something could stop it from being influenced by the spell.
But-
Well.
At least it gave her a little peace of mind while she waited.
It let her feel that little bit more in control. Like she was doing something other than pacing uselessly and waiting for her husband to solve her problem for her.
