CONTEXT
-----------------
I have seen a lot of theories online about the childhood of the twins before being found by wolf. The two prominent ones are:
Vera escaped with the twins after their birth and is currently hiding with them.
The three frog itself is an experiment by bonaparta.
Supporting points:
Hiding theory:
This theory is considered canon so it doesn't need a lot of explanation.
Core issues I found:
1. Why didn't vera chose a faraway place?
2. Why didn't she name the twins?
Experiment theory:
This theory suggest that three frogs apartment was an extension to bonarpatas education program ( Peter capek on seeing the twins just after their birth mentions they will undergo his program) thus monitoring the twins. This also explains why vera didn't run away that far from the red rose mansion.
It also suggests the twins be dressed the same without names to deprive them of their identity.
Also makes sense why vera didn't name them during that time.
Issues with experiment theory i found :
Vera sending letters to helenka as if nothing is wrong which prolly wouldn't happen if they were under the holding of bonaparta.
Schuwald visiting them in three frogs if they were under captive.
MY MAIN QUESTION
--------------------------------------
The thing that bugged me is JOHAN has the nameless monster book with him at three frogs. If vera hated franz and the children have never attended reading sessions at the red rose mansion, how does johan have this book at the three frogs. This only makes sense if the twins were undergoing bonarpata's program, else why would vera allow him to read that?
Please do correct me if I am wrong.
