Bella stockpiles hexes.

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.
