Related to Janice and Jim Wilkins, Officer Wilkins is much less forgiving than Officer Taylor, and he blames you directly for the chaos currently affecting the vault. He is liable to attack as soon as he gives this "lone wanderer" a tongue-lashing.
When the Lone Wanderer returns to the vault in Trouble on the Homefront, Wilkins angrily talks about how much he despises them and their father, blaming the two for the dire situation Vault 101 is in after they escaped, saying, "You never should have left, kid. And now we'll make sure that nobody ever leaves again!" This is most likely due to both of his kids' deaths during the vault riot.
pc If you go down to the basement sub-level during Trouble on the Homefront and enter the room where the Wanderer had to shoot the targets, where you encounter Officer Wilkins, you may find that opening the door and dropping a mine immediately would prevent officer Wilkins from entering his "you should have never left kid" dialogue, keeping him friendly.
