Give the alchemist something to keep her mind busy

You aren't going to chalk up that interruption to a coincidence. She's already challenged the suppression collar and made progress, It's not a stretch to think she might have found some way around it completely. You tell your assistant to get a certain formula ready and meet you at the alchemist's cell.

When the two of you arrive she snaps up with a gasp. You don't imagine she'd react like that unless she was up to something after all. She squints in your direction, seemingly unable to quite make out who she's looking at. You walk in front of her, gesturing for your assistant to approach her from the side before spreading your arms wide and trying to draw her blurry vision towards yourself so that your assistant might go unnoticed.

"So it seems like you're up to more than just fixing your glasses. Well, I've arranged for something else to keep you preoccupied."

You step closer as you talk, eventually getting close enough she seem to make out your shape. She digs her fingers into the wall behind herself, and after some squirming she seems to tear her shackles off the wall and lunge forward. At first it looks like the hunks of metal still hanging on are too heavy for her, making her fall over. However once her palm touches the floor, the surface starts to churn and ripple.

About this time your assistant manages to jab her with a needle, which pours its contents into her before starting to dematerialize. After taking a quick glance over she manages to make you fall on your back and form bonds out of the floor and capture you in the ground. She starts to do the same for your assistant, but the element of surprise is gone. She makes a loop out of the steel floor, but it's not snug enough to grab your assistant's foot.

The alchemist's eyes start to glaze over as the **** your assistant delivered starts to take effect. It's an interesting little mix of opioid and aphrodisiac. Just numbing enough to make movements sloppy and dull the mind a bit. Enough to make complicated tasks like an escape plan a lot harder to pull off. Especially with the distraction the other ingredient presents. As she tries to stand on her wobbly limbs you see her skin start to flush. She manages to get on her feet despite the weight of her detached restraints and being ****. She focuses on the shackles, trying to pull them apart with her powers. It seems to take all of her concentration, which is in short supply as her hands occasionally try to roam her own body before the chunks of metal hanging on her wrists regain her attention by interfering.

You're bound to the floor yourself, but your assistant is free to follow your orders while the chubby brainiac has been nullified for the moment.
