Yeah this tattoo arc is a stretch. Not to mention if the older than dirt tattoo artist just died before they figured it out and came to get it completed, then no one would have ever known the passcode ??
And if the stepson has access to the safe/has it in his possession why not just break into it? Or hire someone to crack it. There's no such thing as an unpickable lock ╮( ̄▽ ̄)╭
Surprised the tattoo hasn't been distorted or anything over time, or was it somewhat recent? (Or do I just not know how tattoos work?)
