She already has a ridiculous number, but she wants so many that if it seems most expedient to individually do some manner of hex-magic to every cubic inch of space in her dorm room, she can and still have a ridiculous number left. She wants enough that if Libby turns out to be a particularly dab hand at extortion, to the point where paying up is her best bet, Bella can keep gritting her teeth and handing over tribute up until the point where even this person will believe that this is all there could ever be - and still have a ridiculous number. She wants her ridiculous numbers to have ridiculous numbers.
What does she have?
An Alice. She has one of those.
And she can use what she has to get what she wants, late into the night, hexily disassembling her body's dependence on sleep, and till she should start thinking about catching up on the internet and heading to class.
Bella starts playing with pentagon-sized illusions, notifying Lazarus each time, and she gives the go-ahead for Alice to rain jellybeans.
It turns out that visual illusions work on him just fine. Also, invisible jellybeans are still tasty.
Bella cycles through some more illusory senses, including touch, since she's not sure if the agony beam is technically "illusory pain" or just disconnected "real pain". Alice gets "trapped in quicksand" and smells "lavender" and tastes "risotto" and hears "Beethoven's fifth". Bella can detect all these things herself, too, where applicable, but she thinks that's probably only because she's controlling the illusions: they originate inside her brain and are allowed to be there on a probationary basis. [Look weird how? Alice, illusion me something, let me make sure it's only mine I can experience.]
[Well, I know what you did 'cause I can read your mind, but I don't see them or feel them,] Bella says, squinting at the ceiling.
Bella shakes herself, chuckling. [Okay, but, what looks weird about illusions to you? Of pillows or otherwise?]
[They don't exist. They are very insistent about that. Absolutely no room for doubt. It's just weird looking at something whose most obvious feature is that it isn't really there.]
Bella laughs. [I wonder if I can wish myself an illusion-detection power? I can imagine blundering into some problems by simply failing to note the presence of illusions when I hadn't been planning to advertise my native power. Then I can look at things that are Obviously Not There with you.]
Bella turns over this notion in her head until she's satisfied with her design, then says, [Watch this, nonbird,] and wishes it.
[I may be anthropomorphizing these things a little too much, but I got the impression your native power went 'oh, all right' and let the wish through.]
Bella cackles. [I do like my power, but I won't hold with it being inconvenient,] she says merrily. [Are you catching any more interesting tidbits about stray magic?]
[Nothing conclusive. I might have to go away and think about it for a while in order to get anywhere. You're right about how convenient perfect recall is, by the way.]
Bella decides to demonstrate her new speed power with extremely rapid solo dance moves, giggling all the while.
