Mark is mostly known for his showmance with Elena Davies known as "Marlena," for being a physical threat, and being emotional. His association with his friends Cody Nickson and Jessica Graf made him a target, and he was accused of flip flopping by the other houseguests. He also clashed with Josh Martinez, by throwing pickle juice and hot sauce in Josh's face. He almost got physical when Josh banged pots and pans in his face. Mark tried to convince his friend Jason Dent to make a move against Paul Abrahamian, but was unsuccessful and Elena was evicted during the Double Eviction with Jason as the HOH. Mark won safety four weeks in a row by winning either a Power of Veto or Temptation Competition, but was unable to save himself during week 8, when he was evicted and became the third member of the jury. Despite his confrontations with Josh, Mark's distaste towards Paul's constant lying and orchestrating bullying tactics, caused him to be one of the five votes for Josh to win, along with Elena, Cody, Jason, and Alex Ow.

What do you think will be the most difficult part about living inside the Big Brother house?
Seeing the same people every day, but I've been through a similar experience studying abroad. Which past Big Brother cast member did you like most: Brendon Villegas from Seasons 12 and 13. He basically said, "It's me and my girl vs. the house. Let's go." Do you have a strategy for winning the game?
Yeah, try to read people and relate with everybody, be real, don't get caught up in stories, earn people's trust and keep it. My life's motto is… Fear none, regret less. What would you take into the house, and why?
