EastEnders viewers were left questioning what would happen next, as Max Branning made a deadly discovery during Friday's episode.

He managed to work out that Sharon Watts seemed to be the person behind Ian Beale's ongoing ill health.

Viewers know that Sharon was behind his recent attack, after he was hit over the head and left for dead.

Sharon, knowing the truth about Ian's involvement in the death of her teenage son Dennis last year, asked Phil to kill Ian.

Sharon has since been poisoning her husband, and after he began feeling unwell he went to the doctors.

Of course his wife feared the worst when the doctor suggested blood tests to find out why he was feeling so unwell, unable to do anything for himself.

Given he had recovered from his injuries, Ian was worried something was up - and he wasn't the only one.

As his mum Kathy shared her concerns with Max, he went into the pub only to overhear Sharon postponing Ian's much-needed blood tests over the phone.

Max told Ian it was Sharon behind his ill health

She told the doctor that he was fine and they were going away, delaying the tests for a month.

A suspicious Max questioned her reasons, knowing Ian's attacker was still out there - and he came up with the theory that she was trying to kill him.

Given Sharon's recent behaviour, Ian's ill health and the fact she was isolating him from his family amid her plan, Max visited Ian and told him he believed Sharon was up to no good.

Ian told him he didn't believe him, but it was clear his words had made him think.

Viewers were happy that Sharon might be exposed, but some feared the consequences on Max given the character is bowing out of the show this year.

With no details revealed on his departure, many questioned if Sharon would frame Max for the crime and if Ian might even help her - despite her already framing missing Tina Carter for the attack.

Others questioned if Sharon might end up silencing Max to keep him out the way, so she can go through with her plan to murder Ian.

One fan tweeted: "Yes Max! I knew he would see through Sharon! But I’m sure she’s going to frame him now."

Another said: "And you just know that despite Max helping him, Ian will still help Sharon frame him when the truth comes out."
