In this case, the protagonist is meant to stay in solitude for 1,200 years. How is he going to do that holed up in an office building? Isn't partial integration into human society a more effective strategy at keeping away from disaster zones and other issues if one's mission is so important? The episode ending seems like a downer but I don't see practically why it's so bad. 1,200 years to learn social skills is plenty of time.
Slave to the Patriarchy no more
