It’s pretty fascinating to me that Simon mentioned prison considering one of the possible meanings of Louis’ spider web tattoo. From Urban Dictionary:

“The symbol of the ‘spiderweb tattoo’ means the wearer has, or is currently "doing time.” It is most commonly seen on the elbow, neck, or knee. However, one might find this symbol almost anywhere on the body, the placement of the tattoo itself makes no difference. Usually this symbol means that the wearer has done time in jail, or prison. This specific symbol is used to show time locked up, because the spiderweb itself symbolizes how a spider web catches, or imprisons it’s prey. These days inmates will wear this tattoo to look the part of the “tough guy.”

This tattoo can also mean “struggle.” If one has been through a certian struggle in their life such as; overcoming a drug addiction, getting out of a gang, or even getting out of prison/jail.“

     “After I got my first tattoo on my back, I was walking down the street in San Diego, and—I’ll never forget this—a guy across the street yelled at me: ‘Did you just get out of prison?’ Are you serious? I’m this little 18-year-old girl, and you’re a grown man!
     “But at the same time, I also had to fight with my mother because, in her Mexican culture, only drug addicts, prostitutes, and prisoners got tattoos. It took me a long time to finally tell her, ‘You know, I don’t do drugs, I don’t drink, and I’ve never been in jail. I just like tattoos and that’s my only vice in life.”
