This week both Louis and Dan celebrate their birthdays in very different ways. It's also Friday the 13th, but will it be a lucky or unlucky omen for the studio?

Sexy portrait expert sexy Sylvia Z takes a guest spot in the studio and apprentice Rachel comes under scrutiny from the guys, is she really up to the job?

Tensions run high at the studio. Louis loses it with Dan who is forced to do a tattoo design he hates, Phil loses it with a client but Nikole does one of her best tattoos.

With Nikole away the boys decide to have a lad's night out at the dog races. Louis is suddenly out of his comfort zone Dan takes the bookies to the cleaners.

Louis thinks Dan spends too much time yakking with his clients and not enough time working. The shop holds an Apprentice Challenge in order to pick the best candidate.

London Ink's doors open to clients and Louis recalls how he sketched out Beckham's Guardian Angel tattoo. Dan the graffiti guru reveals his troubled past.
