This time, they want to get a cover-up on one of their respective tattoos. Joey throws a curveball by giving all the artists the same prisoners. Maddie is picked by the Human Canvas Jury as the worst tattoo of the day, and Mike ends up in the bottom, but Frank's poor tattoo sends him home.

• Elimination Tattoo: The artists must try to bring texture in their phoenix tattoos. James Danger's canvas did not see eye-to-eye with him. She walked out, resulting in no canvas for Danger to showcase his ability upon. The judges interviewed both Danger and the canvas to see what the problem was; after which it was determined Danger could not handle the nagging personality of his canvas. The judges agreed that being an Ink Master, one would need to know how to instill confidence in their client, and should have the skills to do what is requested. They also factored in his Flash Challenge tattoo of a leg garter which was poorly detailed and rough in different areas to reinforce their decision to eliminate him. This is the only episode where no one got Best Tattoo of the Day, no Canvas Jury, and no Judge's Recall due to the incident Danger had with his canvas.

Chris, Craig, Jason, and Made Rich's tattoos were overly dark; with Craig drawing additional criticism for mixing black and white ink for the gray shading (a faux pas in the industry). Tatu Baby executed a good design but failed on detail. Joshua, Joey, and ES came up short on their usage of black. Jackie and Jime were the only artists who got praise from the judges. Chris ended up having to close shop.

• Finale Tattoo: The artists tattooed pinups on an unusual canvas. Turns out that they are the contestants from Season 2. Each artist, except Kyle and Josh who both chose their own canvas, will consult with all the canvases for five minutes. The canvases picked the skull containing the number on the bottom that will determine the order of who gets to choose their artist. During the elimination, Tatu Baby mentioned she was ready to drop out because of embarrassment from poor work over the past few episodes. She was disappointed in herself, however the judges convinced her to stay on board if she was not voted out. Joshua and Craig were also emotional about the degree of challenges they faced, and the results thus far were not what they expected. Craig's elimination was the most controversial elimination in the show's history as both Jime and Tatu Baby were in shock of the judges' decision on Craig's elimination.

Second Artist Advancing to the Finale: Joey Hamilton

Third Artist Advancing to the Finale: Tatu Baby

• Eliminated: Kyle Dunbar

• Elimination Challenge: The three remaining artist must apply a tattoo incorporating each skill tested on throughout the season. They have the flexibility of location of the canvas, studio to apply and design of their application. Other than the other standard rules, the artists each have 35 cumulative hours to complete their work.

The live 2-hour finale started with a quick recap. It transitioned into the 2 artists who received the highest number of audience votes Chris May and Kyle Dunbar. These two artists had the opportunity to apply a tattoo live in a battle to be the returning contestant for Season 4. The time limit was 6 hours to complete the tattoo. Maddie la Belle was excluded from the voting due to pregnancy. And James Danger was also excluded from the voting process due to personal reasons. In addition, he was not present during the finale, making him the only contestant to not return to the live finale as a guest.

The remaining artists and finalists were brought on stage, and the judges offered the chance to discuss their reasons for participating in Ink Master. Josh was given solemn advice by other contestants and judges regarding his attitude. The canvases throughout the season were also given a voice, and some returned to the finale to make comments which ranged from praise to arguments with the artists and judges.

The judges decided to produce the vote tally for the various artist levels of popularity during the live finale. They also reviewed some of the controversial eliminations and season tattoos. The person with the highest number of votes throughout the season received a guest artist spot at Peck's and Nunez's respective shops.

By this time in the episode, the time limit for Chris and Kyle's tattoos had expired. Kyle's tattoo was liked by the judges, with the one criticism of needing to use more black. Chris's piece received a positive review as well, and both artists were asked why this quality of work was not produced during the season. Chosen solely by the audience, the winner and recipient of a season 4 contestant seat was Kyle with over 170,000 votes. The show lead to interviewing the three finalists, starting with Tatu Baby. She discussed her challenges and thoughts during the season, and was glad she did not quit. Joey Hamilton expressed his joy to have made it to the finale and in classic competitive fashion, compared himself to the other two finalists. Jime rounded out the trio with his comments and expression of excitement.

Tatu Baby's back tattoo was first up: a partially nude Native American woman with a wolf. The judges found it satisfactory overall, but had issues on its placement and continuity, and pointed out some areas that should have been tighter. Joey's design was a partially nude mermaid in an aquatic environment on a leg. The design was missing some contrast and would have benefitted from additional black to bring out the emotion and depth, but the time spent showed through. Jime did a full chest/stomach tattoo of a traditional battle royale; however it appeared dull and lacked punch. The coloring could have been better, and the background overcrowded and overshadowed his primary artwork. Despite a rebuttal, the judges' criticism remained, and he was chastised for not sticking to his area of expertise for this open challenge.

• Winner: Joey Hamilton
• Runner-Up: Jime Litwalk
• Third Place: Tatu Baby
