The third point of view:
Isabella was grateful for the fact that those little troubles - Allen, Ailee, and Neon- had left them alone. She loved them but God, they were so exhausting. Had Niklaus felt that same way with her when she was younger, Isabella doubted it. Compared to the twins, she was more quiet and sensible.
Aside from that, she needed time with Pedro. It's been so long since she had a one on one date without the company of others ever since they came to Lincolnshire.
So when Akim suggested they take a tour of the palace during their free time, Isabella had accepted without hesitation - that was the fastest way to lose the kids.
As expected of the palace, it was ridiculously large with a large mass of land and a total of five hundred rooms. Doing the calculation, Isabella couldn't help but shake her head. So many resources.
