For me, this is how it all unfolded.
In EP2, the windows break when the Alphas throw the dildo for the first time. Rusty asks dad and dad pays. But Papa also gives Rusty the emergency money.
In EP3, however, Rusty makes a mistake. He spends the emergency money to visit the Pink Rose. He rented the whole Pink Rose for the evening, which must have cost a lot of money. So he wastes the emergency money on himself and his brothers. If the father had found out, I'm sure he wouldn't have been thrilled.
The mansion is destroyed in EP5. Rusty asks his father for money. He refuses to pay and tells Rusty to use the emergency fund.
I have a feeling that Rusty's father knows more about what is going on in the mansion. He is forcing Rusty to do something or give up. Thanks to the MC, Rusty doesn't give up, and the DIKs finally start to take care of themselves. Papa Burgmeister's plan is working.
What was Rusty's father's plan? Rusty and the MC once talked about how fathers prepare their sons for life in different ways. The MC can fix things and Rusty studies business administration. But one thing Rusty was never taught. That you can't rest on your parents' accomplishments and SOHN is not a job.
Look at the following pictures and read the text that is written with them. In the pictures you can see a Burgmeister and a Burke. At the EP5 prep party, Stephen Burke and Geoff are also in the same room. Stephen is the father of Tybalt. Is Geoff perhaps the father of Rusty? Yes I know, many assume that Geoff is the father of Arieth and therefore Rusty cannot be his son, because then there would be incest. But this is only assumed by many and is not yet confirmed.
I come to the conclusion that Rusty's father wants to prepare his son for life and for this he talked to Stephen Burke and Stephen teaches his son Tybalt with it. Either save the nerds or build something new. Only Rusty doesn't do so well with rebuilding, because until the MC comes along, he still has SOHN as a career choice.
Let's get back to the destruction of the mansion. What does the MC's grandfather do for a living? He builds and renovates hotels. Is the destruction of the mansion a test for Rusty and the MC? The MC saves the DIKs, and Rusty could have saved you nerds, too.
Something comes to mind. What if Rusty's father is Lynette's brother? That would give the grandfather a once in a lifetime chance to test and/or prepare his two grandsons for life. And all in one fell swoop.
