"Ink Master" season 4, episode 13 spoilers are up and the top three contestants will face a grueling challenge that will last 35 hours as the show winds up to a close. Evicted Halo, meanwhile, has expressed his willingness to return to compete again in season 5.

With only the favorite Scott Marshall, Sausage and Matti Hixson remaining, the show's producers are pulling no stops to the challenges they are going to put the contestants through for the show's season finale.

The winner will get the grand prize of $100,000 as well as the distinction of being one of the top tattoo artists in town.

According to the "Ink Master" season 4, episode 13 spoilers, Scott, Sausage and Matti will work on a 35-hour grueling challenge on the back of their respective canvasses. They will work on the tattoo, which they design on their own, for a couple of months.

"Ink Master" season 3 ultimate winner Joey Hamilton will also make an appearance to ink a live canvass in front of everybody.

While the evicted Halo has not provided any "Ink Master" season 4, episode 13 spoilers, he told Matt Carter of cartermatt.com that he would be willing to come back on season 5.

"Unfortunately I do not think it would be the same though," he said. "There is something about the dynamic of the people you interact with the first time around, and I feel like doing it again with completely different people definitely adds on a stress factor that I did not have the first time."

In the last episode, the contestants worked to cover the scars of breast-cancer survivors as well as covering up the mistakes made by some of the contestants of the show such as King Ruck, Gentle Jay, Melissa and Jim.

Sausage won the best tattoo of the day, which immediately earned him a spot in the finale.
