I agree with your point and know Phineas means well but doesn't seem to get the whole picture and them letting Perry go will actually lead to more danger. I also dislike how Perry's own views and autonomy in this whole situation isn't considered at all, makes Perry to be an outsider in the family despite all she has done for them.
Theo not letting Perry go in this situation despite it being motivated by his irrational obsession or affection might actually be the better decision compared to Phineas's rational one.
I understand Phineas being worried for Pereshati since she was constantly put into danger because of being part into their family. Pereshati have been quite traumatized or yet struggled a lot when she started being involved with the family and she is yet also will still be put into danger after but letting Pereshati go out of the household will be risky considering the princess is somewhat a freak and obsessed with therdeo, She wont just let Pereshati live or yet make her live a normal life just because the family would let her go. High chance she would be more in danger and also a chance of her dying☠
Pereshati has been helping and improved their family and yet was willing to risk her life just to help them so I honestly dont blame Phineas for what he thought that would be better for her since she did almost die but he never thought of how it is more dangerous for her to leave the family.
