Besotted Arg has been working hard to win back ex-girlfriend Lydia ever since her return to the show earlier this year.
Viewers have seen the pair work towards making their relationship official, and after enjoying a holiday romance in Ibiza, Lydia even admitted that she was still in love with him.
However, it appears Arg's lack of maturity remains Lydia's biggest concern.
In tonight's episode (22 October) of the hit Essex-based reality show, Arg confesses to James 'Lockie' Lock and Dan Osborne that he is worried about letting Lydia down.
Later on, Arg comes face-to-face with Lydia at Sugar Hut nightclub and she has stern words for him.
Will the childhood sweethearts be able to move past this latest obstacle in their romance?
The drama continues in The Only Way Is Essex, exclusively on ITVBe on Wednesday 22nd October at 10pm.
