Veronica and Greville's Relationships

Veronica has agreed to take medication prescribed by a visiting psychiatrist. But the lithium and flufenosine she's taking only seems to have made her worse. She fears his next step is to have her committed by force. Veronica hates the pills, but they seem to have got john off her back. He's even commented on how much brighter she looks. You can't help but feel that's just what suits him, rather than good for her.
