Finally she spins on her toe to face Winter, who may still be on the floor in his careless way but has surely recovered from the blow by now. "You," she says, "must go to the lion, and tell him that I desire safe conduct to treat with him on a matter of as much importance to him as to me. Go peacefully, I do not mind if you alarm the pitiful creatures who side with him but do not harm them while I seek parley. Do you understand, my Winter?" She bends to crook her first two fingers under his chin to turn his head up for frigid eye contact, inspecting him, thinking furious thoughts to which he's only an accessory. "I think the lion may be unnerved to see you. We will see."
"What did -" But there is an atmosphere suggesting that this would somehow be a deeply personal question to ask of Aslan. She swallows it after those two words, and goes unanswered.
Bella fills in her current best map when he mentions places, and takes notes as they walk - it turns out her staff still works tucked in her elbow even if she doesn't touch it to the ground step by step, so she has a hand for the notebook and a hand for the pen - but asks: "Aren't you going to be there to lead everyone? Are we going to be handling detachments and need to coordinate?"
As soon as Bella asks the question, James suspects she knows the answer. But she waits for Aslan to speak.
"I suppose there are a tremendous number of countries that need your attention or Narnia wouldn't have had such a long winter at all," says Bella. "And you might be called away. So if we can handle it we should, but it's only we have not actually commanded armies before. Are there more experienced creatures who could do it?"
Yeah, James has her suspicions about that noncommittal answer. But presumably Aslan has reasons. She pays close attention to everything he says about the coming battles.
It occurs to James that making camp on this side of the river is an interesting choice, but she doesn't say anything.
"Hadn't we better go ahead and ford it," says Bella, "so if the Witch's people come at night we'll hear them splashing?"
Bella doesn't seem to be picking up on any inferences, she's just sort of moping on the reconstructed cushion heap, looking at her map in the dying daylight.
"I think Aslan's going to go let the Witch do something to him," James murmurs. "And he's bound to have some kind of plan that makes that a less obviously stupid idea than it sounds, but I have no idea what it is."
"...What - let her hurt him instead of you? I guess she'd take the bait, she hates him like nothing else, but - I hope you're right about the plan."
"It'd have to be something that she doesn't expect - or maybe she expects it, but the whole arrangement will still let her do something she can't resist?"
"I could probably manage it if I decided it was definitely a better idea than seeing what Aslan's up to for sure," she says. "I'm not sure I've decided that."
