I do agree that I feel as though furthering Lucy's story would be nice. To be honest, I was expecting some form of a follow-up 'retaliation' from her mother, to be honest. I mean, the cafe is really close to where she lives so there is no way her mother doesn't know where she is currently staying.
The challenge, I imagine, would be maintaining good pacing. Especially considering we are in the middle of establishing the dynamic between the MC and the other Founding Family heads and their daughters (Sarah, Hannah, Cathrine and Elizabeth).
