It's tricky. Getting into and out of her rose-sphere is routine after a few days, but she still hasn't uncovered an explanation of how channeling works, though she's been informed that there are three options for how to do it (by herself, through a willing helper, or through an unwilling helper). Unlike the fourfold options for reaching the Dreamworld, this does not tell her how to begin fumbling towards a practical understanding, even though she can rule out the last one just on the basis of its description.
Beast can only do so a tiny bit of reading per day, and her pile of books that she can read shrinks much faster than his. She combs the library for multilingual dictionaries, so she can pick her way through the titles of the foreign-language books and at least prioritize them before handing them over.
Finally something in an obscure language that even Beast can barely read - Belle has to look up a lot of words - explains the channeling in a way she can understand.
"Weird," she mutters. And she breathes in air and breathes it out as visible fog. "Well. It's still frigid in here but at least you're warm." She snuggles up comfortably.
"...That's a common saying, yes, do you just mean it's been a long time since you got to hug anybody and now it's a big deal?"
She naps for about an hour. During that time, the air starts to warm, and she unconsciously wriggles, trying to divest herself of her blanket.
That lets her get the blanket off, but then apparently she's too cold; still asleep, she wraps her now-free arms around him and settles in closer.
Eventually she wakes up. She yawns. "Is it just me or is it warmer in here?" she asks.
"Here's hoping that's the only trick up its sleeve." She slides out of his lap. "Maybe it'll give me a longer dress now. And then I can just keep it on until I'm satisfied that's the last time the castle pulls this." She runs up to her room to check.
Excellent. She changes out of her three summery ones and comes back downstairs in a nice burgundy number, ankle- and wrist-length. And she sets about reading. "I'm sorry if any of how I reacted to that was - rude, or callous, or something," she says.
