The 22-year-old nightclub promoter's mum Tina took her own life when Essex was only 10 years old, and he becomes emotional as he looks through old family photographs with Faiers.
Essex tells Faiers: "I just wish I had a mum... I just miss her. If I see a picture, it just upsets me."
He also asks her if she will visit Tina's grave for the first time with him, as Mother's Day approaches.
Essex paid tribute to his mother on Saturday (March 2), writing to thank fans for "all [their] kind tweets" on her birthday.
The Only Way Is Essex airs tonight (March 6) at 10pm on ITV2.
