When the party has died down, Isabella, for one, is well and truly exhausted. She explores the palace until she finds a room with a bed in it, and into this bed she flops, still in her clothes and holding her staff and carrying the cordial in her pocket. She sleeps late, because the party kept her up so late and she hadn't really slept the night before; but around noon, she stirs, and gets up, and goes looking for James and wherever her backpack may have got to. The backpack she finds in the great hall where the principal mass of the party was; some enterprising creature took both bags from the battlefield at Beruna up to the castle for them, and she only wishes she knew who it was. She takes her bag to her room and carries James's with her and continues looking for her friend.
And that evening Isabella gets a copy of Alice in Wonderland out of her magic bookshelf and brings it to the dungeon.
There is a marked map and a pen sitting by the bars, behind Winter, who persists in facing the wall.
Isabella takes the map and pen, and puts the book through the bars.
"I have a magic bookshelf, so I could easily get a copy, and if you must be depressed at least you needn't be depressed and bored."
"And yet that does not explain why you brought me Alice in Wonderland."
"James didn't seem to think it would be a worse idea than her doing it."
"Well, I'm not scurrying up the stairs in regret yet, I don't know if you'd have preferred her to visit rather than me."
"Are you unconscious while you're stabbed through the heart?"
"All right then, I won't offer to periodically toss you an icicle."
"To stab yourself with. Apparently it wouldn't be an improvement."
"One of us will be back later to swap the book out, if you think of another you'd like." And Isabella heads for the stairs.
