The former couple have been spending plenty of time together since Lydia returned to the ITV2 show at the end of last season – and it's clear there is still a spark there.
On last night's show, we saw Lydia telling her pal Ricky Rayment: "I would love to give it another try, I just don't want all the complications, you know?"
When asked if she'd ever get back together back with Arg, she replied: "I don't know. I can't predict the future can I."
So that's a yes, then?!
"No! I didn't say yes," she said. "I can't predict the future. Who knows. In ten years time we might be married and have kids. But that's years away."
Ricky replied by saying that means she has left the door open and encouraged her to look at how far she and Arg had come in just four weeks, then think what might happen in another four weeks and another…
When Lydia returned to TOWIE it marked the first time she'd come face-to-face with Arg in nearly two years.
Last night, we saw the pair returning to The Duke of Essex polo tournament with their co-stars. It was actually at the event six years ago that they first met, so it's no surprise plenty of feelings came back…
They discussed how they'd spent the night dancing and kissing – and how Lydia accidentally sprayed perfume in her mouth thinking it was mouth spray. Oops!
Arg, however, kept kissing her. Ha!
He also revealed he later found out Lydia had kissed another two guys that night. She looked a bit embarrassed by that memory!
"After all the drama, tears and tantrums, I'm still glad I met you," she concluded.
