Callum Highway has made a significant discovery about Jay Brown in EastEnders.

For several weeks, Jay has been drawn to a sex worker named Nadine because of her physical resemblance to his late wife Lola Pearce-Brown.

Jay has started to wander off in the middle of the night and has ended up employing Nadine as a non-sexual sleeping companion.

His disappearances became a source of conflict in Thursday's episode (October 5) because Ben Mitchell wanted to know where he was going at night when he should be with stepdaughter Lexi.

What to Read Next

Jay refused to give Ben any straight answers, so Callum felt like he needed to try his best to reach out to Jay on a more empathetic level. However, Jay also brushed aside Callum's questions to insist that he'd simply been going out at night to connect with some new friends.

Callum wasn't convinced but had something else come up when he ran into Nadine and she tried to pick him up. He revealed his identity as a cop to dissuade Nadine but he ended up amused by the ordeal.

Soon though, Callum wasn't laughing as he spotted Jay speaking to Nadine and following her into her flat. The realisation dawned on the copper that Jay has been seeing a sex worker at night.

This storyline is set to take a gripping turn in the upcoming weeks as Jay starts using ketamine, at Nadine's recommendation, as a way to dull the pain.

It won't be long before someone discovers Jay is using drugs, but can they convince him to get the help he needs for his grief?

EastEnders airs on Mondays - Thursdays at 7.30pm on BBC One. The show also streams on BBC iPlayer.
