If you ask me to tell you, it’s neither of them.

After replaying it several times, I discovered several important pieces of evidence.

1. When the player meets Krog for the first time, he starts a series of conversations with him without any secrets, and then the battle begins. If you don't kill him immediately but kill the surrounding adults and then wound him, he will find cover after a while and shout to you: "Your son is dead! You are wasting your time, you Don’t you realize it?” Something like that.

2. When you enter Krog's memory, when thawing in Vault 111, press E on any cryo chamber to start Krog's inner monologue. Krog says "Why?" To unfreeze everyone, we only need one in the end, maybe the old man (college) doesn’t want things to be complicated.” Click on the player again, and he will say "Leave one (player). If things don't go well, we have a spare tire before, but this is wrong. As a father, if this person can defeat me, the academy is not his." opponent". In an earlier memory, we learned that Krog had a daughter, and Krog felt guilty saying that he was not worthy of this daughter, and that he could not promise to give them peace of mind and safety. To connect things together, the old man from the academy ordered them to go to Shelter 111 to get the baby, but they thawed the child. Kroger didn't understand why, so they just unfrozen c6 (Shaun). Then Krog said that keeping a spare tire (player) was also a wrong decision. He knew how dangerous it was to leave a father who had witnessed all this and avenged his son. All this is the decision of the old man of the college. So who is this old man from the academy? If not father.

3. In the last memory, he and 10-year-old Sean were hanging out in Diamond City, like a father and son. He also monologued that he didn’t know why the old man wanted him and 10-year-old Sean to be together. Sean, who is 2 years old, lives like a father and son in Diamond City. The radio behind him keeps saying that Piper's news about synthetics has caused a lot of panic in Diamond City. People are afraid of the third generation of synthetics. The problem is Coming. 1. If Sean was 10 years old at that time and is 70 years old now, then why the ages of Piper and Diamond City radio announcer Trevor have not changed. 2. The issue of the third-generation synthetics causing panic in Diamond City only happened recently. You can learn from Nick Valentin that it was not long ago that a malfunctioning synth pulled out a gun and killed someone at a Diamond City ramen restaurant, and it was finally revealed that he was a synth. 3. If the 10-year-old Sean in Kroger's memory is already a synthetic human, then Farther said that synthetic children are just prototypes and there are still many unstable factors. The academy has already had many synths who have escaped, become self-aware, rebelled, and malfunctioned. Why would the academy take the risk of sending a prototype to live outside for a few more years? And it is known that Kroger and 10-year-old Sean have been living in Diamond City for some time. But if you choose the other camp ending, you can rescue the synthetic Sean, but he will say that he has never seen the world above the ground, which is illogical.

Finally, I learned from Farther that he knew he was going to die less than a year ago. He told the protagonist that he wanted to meet his parents, and he wanted to experiment with what his pre-war parents thought of this new world. It's basically a lie to the protagonist. Because it was written in Krog's terminal that the academy believed that letting a pre-war shelter dweller like him out would not be able to survive in the wasteland. Even if the wasteland did not kill him, Krog would kill him. Krog can kill synths with his bare hands, but players die n times in the game. As long as they play the main line at a normal playing speed, the player's level is not very high when fighting Krog, and there is a high chance that he will die. Then the question arises. The college's work style is very rigorous. If Farther is about to die, he wants to know what his parents think of him and how he thinks of the wasteland world before he dies. Instead of directly teleporting the player to the academy for isolation and conversation, he let the player out to be killed repeatedly. Finally, the academy's top killer Krog came to fight the player. It's like you are dying and want to see your father, but you hired a driver without a driver's license, drove a car with no brakes and no seat belts, and drove your father speeding all the way back to see you. Do you think you What is the probability that you will see your father alive to see you for the last time and share your thoughts and what you saw and heard on the road? This is simply a failed plan and a meaningless experiment.

But the academy made a series of preparations and finally convinced all the players that Farther was just a player, and Farther persuaded the players to stay and join the academy. Or maybe it was true what Kroger said. The old man ordered them to take away the baby but left a father who wanted revenge, which was very dangerous. If this father died in the wasteland, we would have one less thing to worry about. If this father can kill Kroger and still recruit the academy, then before Farther dies, he can find a strong candidate to replace him and make the academy more efficient in the future. I think this statement is the most logical and convincing.
