I want to hit Dad! However, he only goes unconscious so that won't work. However, why is there no speech dialogue to tell your dad that because he left, he caused a rift in society and many people died because of a radroach infestation? Having the only doctor leave made things worse. He then asks you why did you leave the vault, but there is no option to say"I didn't have a choice, it was either get killed or go after you! The Overseer wanted me to GTFO."
My happy life in the vault was ruined because of him! I was doing so well as the vault chaplain! I was destined for great things being a servant of God! Now it's all ruined and I can't even express my feelings.
Man, if only we could have asked these things...
