Her condition seems to be out of control. If they could control it with medication they would have done it already.
There will be no “sympathy factor”. If she is not healthy 2 weeks from now it will become obvious to everyone that she’s been lying the whole time.
Note that there have been no 20-second photo-ops since Canky left Chel's, to walk unattended the length to the Scooby parked purposely a good distance away.
Suspect that they either don't want to over-expose her doppelgänger, or consider it too risky to over-drug for another photo-op.
Furthermore, where is Canky now? She left Chel's to go where, exactly?
