you lock the door on the bunker to save carl the npc and yourself from the tangomangles from giving you free chicken nuggets, but they use the key to enter, you take them out, but carl judges you cause he didnt know the truth, but you tell him it, and he's sorry...

Oh I thought, I thought you did forget to lock the door. you: (It's locked!) But you didn't, you remembered it was the key. you: (Yeah!) Oh I thought, I really thought you were an idiot. But it turns out, that I was the one who's an idiot. It was just them! It was not you who was the problem. I judged you too soon and left the truth. I didn't know they used the keeeeeeey! I didn't know they used the key! Oh yeah! I know I'm wrong, I swear I didn't know, That's why I'm sorry my bro.
