When Lin and Emily were both trying out their CLLR Pro 2's, they tried experimenting with the various modes it had to offer, one was "Limp Mode", making the user of The CLLR Pro 2 go completely limp (with exceptions of very specific body parts).
Unfortunately, they intended to only enable Emily's CLLR into this mode, but didn't think about the fact that Lin was also wearing her own CLLR and had "Duel Mode" active, meaning both CLLR Pro 2 devices could be controlled using the app at the same time. Enabling the mode meant both their CLLR's activated and their bodies gradually turned silver from the CLRR's nanobots. Lin couldn't do anything, the CLLR was not capable of being disabled while it was activating, inevitably leading to their minds being possessed by the CLLR's nanobots as both of them went totally limp.
Thankfully there's a timer which can be set to-- oh .. I think she might have forgotten that too. Ah well, the device will automatically disable after 12 hours... Or is it 24? .. 48?
Luckily for them their minds are completely blank and wont remember a thing (unless she's enabled Memory Mode).
