We previously found out that mysterious Andy is kind-of related to Ronnie Mitchell.
Remember Danielle? She was Ronnie’s daughter, but Ronnie’s father (Archie Mitchell) tried to keep the pair apart, and just when they were going to be reunited, Danielle died.
But of course, this is EastEnders after all.
Well it turns out that Andy (Jack Derges) is apparently Danielle's half-brother.
As if Ronnie Mitchell (Samantha Womack) hadn't been through enough already. Ever since Andy joined Albert Square - and we found out that he had a file on Ronnie - we've been wondering what he's doing there.
But earlier this week viewers weren't really thinking about what his ultimate plan is, because they were a little distracted...
The episode caused quite a stir with Eastenders fans on Twitter, and here's just a few of the reactions from the viewers:
We have to agree, he is rather good-looking isn't he?
What did you think of topless Andy?
