Ami & Nunez are buying a bar, but disputes with their business partners threaten to keep the bar from opening on time. Garver and Kat team up for a tribute to Erik's sister. And Amy wants Ami to add more skulls to her collection.

Ami and Nunez pay a visit to the guys at American Chopper to settle a beef and do some tattoos. Ami gives Paul Sr. a portrait of his dog Marty. Nunez helps Paul's girlfriend Beth celebrate her 50th birthday with her first tattoo.

Kat's friend, Mike flies in from L.A., and Ami gives Mandie an old school tattoo. Darren helps Lucy mourn the passing of her little brother. Tensions continue to run high in the shop between Ami and Kat. What will happen to Kat?

Now that Kat's gone, Ami and Nunez have to find someone to fill her spot, and fast. They spread the word and the first artist "try-out" is the beautiful Tasi Lyn from Long Beach, California. Meanwhile, Garver helps Encina perfect her vampire look.

Not only are the guys down an artist at the shop with Kat gone, but the continued success of Love Hate means Ami & Nunez also need more staff at the bar. In the meantime, Ami helps Marissa put an end to the single life with a double happiness tattoo.

With the shop down an artist, Garver's old friend Tim Hendricks joins the team as a guest artist. Ami treats Samantha to a traditional owl tattoo to honor her grandmother. Garver gives BMX rider, Matt a bearded back piece.

With Kat gone, we try out NYC based Miss D'Jo as her replacement. She hooks Chris up with a film themed family portrait. Darren gives Humberto a massive phoenix, symbolic of his ability to rise above a volatile childhood.

Garver agrees to paint a piece of art to hang in a model home. Yoji gives Jasmine and Ali matching tattoos to show how much they are in love with each other. Meanwhile, Nunez tattoos a real-life mermaid.

Ami and Nunez head to Las Vegas so a major promoter can teach them the tricks of the trade and throw a party for their bar, Love/Hate. While they're away, Darren's pal, acclaimed tattoo artist Joe Capobianco, fills in at the shop.

Ami and Nunez try and find a balance between working days at the shop and nights at their new bar. Unfortunately, Nunez enjoys working the bar a little too much and his irresponsible behavior pushes Ami to the edge.

Nunez and Ami's partnership has reached the breaking point and the boys need to decide if they're better off as friends. Garver takes on Simone's elaborate peacock tattoo while Darren gives a 300 lb woman a voluptuous pin up girl tattoo on her back.

With the stress of finding Kat's replacement, running the shop and managing the bar bearing down on him, Ami's having a tough time controlling his temper. Yoji almost loses it when he rubs off a stencil for a Koi he's working on.

Yoji's been bulking up with workouts and weight gainer to combat Ami's bullying. And when mixed martial arts fighter, Paul Buentello offers to help him train, Yoji's in for a serious beat down in the ring.

Ami sends Nunez to drag racing school to cure him of his inner 'speed demon' and his pile of speeding tickets. He's a natural, and shows us what he's made of in a head-to-head race against a pro driver. Miss Kim drops in for a guest spot at the shop.

Ami and Nunez help out the home team by creating a temporary tattoo design for the Florida Marlins and their skills get put to a major league test when the Marlins ask them to throw out the first pitch.
