On tonight's episode, the pair finally have a chat, but does it go well?!
As viewers will know, Debbie's daughter Lydia has had a rocky relationship with Arg to say the very least. The pair started off on the show as a couple way back when TOWIE first aired and things have been on and off between them for a whopping seven years.
The last series saw the pair pretty content, with talks of marriage and buying a house together, but they broke up again just before the current series of TOWIE began.
Speculation suggested Arg's return to his partying ways had sparked the split and Lydia's co-stars admitted they thought it was the final straw for the pair. Bobby Cole Norris revealed: "I do feel like this is the end of the line for them, though. When you've been together from so young, you either grow together or grow apart. Either way, good luck to them both."
When the new series kicked off, Lydia came face-to-face with Arg on the beach in Marbella and said to him: "I just think moving on from now I deeply don't want us to ever be friends. You're not the kind of person I want to be in my life. My life is my life now, and I'm getting on with it, we'll keep it that we're strangers. We will just walk past each other and that's how I would like it. I don't want to know you anymore."
On previous occasions when the pair ended things, Arg always kept in touch with Debbie and would often meet her for a catch up and advice. But this time, he's kept his distance from Lydia's mum, until now.
We're not quite sure how this one is going to pan out, bring on tonight's episode!
TOWIE airs tonight at 10pm on ITVBe.
