What’s behind door #2?

It was late and I was tired. I was on a quest to find some unique items to have for my base. Just walking around the entrance floor of the Dam and noticed I could finally see what was behind the locked door in the bathroom! It had always bugged me I couldn’t look inside and no matter what angle I used while crouching I could never see anything.

Would there be something unique? A lost survivor? The irony of a crowbar? Sometimes the mystery is better. ☹️
