Emmerdale's Caleb is on Joe Tate's case in Wednesday's episode (ITV, 7.30pm, see our TV Guide for full listings).

Currently believing Joe Tate is a hero who 'saved' him when he was carjacked and stabbed, is Caleb about to find out Joe was actually behind the grisly crime?

Having already started to feel suspicious about his nephew, alarm bells ring when some meds fall out of Joe's coat.

Spotting Joe's panicked reaction, Caleb realises he's clearly got something to hide and starts digging around in earnest.

Top of his list is Noah, Joe's half brother.

Summoning the sparky to the depot on the pretext of a broken light, Caleb gets Noah talking.

When Noah starts opening up about the night he was spiked, chills run down Caleb's spine when he starts talking about his weird visions of a hospital and hazy recollections of Joe being involved.

Is Caleb about to work out the terrible truth about what really happened to him that night?

Elsewhere John Sugden's got his work cut out as he tries to make it up to Aaron.

With Aaron starting to tire of John's horrible moods, the medic opens up and admits to his faults.

As John admits he has problems with control, is it enough to win round Aaron? Is the wedding still on? And if so, is that wise?
