The market boss obviously isn't impressed to learn his girlfriend has been sleeping with her comatose sister's husband.
So when Roxy learns of Aleks' plans to propose, all is not what it seems. She returns home from visiting Ronnie in the hospital, preparing herself for his question.
But no amount of warning could've prepared her for the one he asks.
When he produces the ring, instead of asking Roxy to marry him, Aleks questions how long her affair with Charlie has been going on.
Will a clearly stunned Roxy come clean, or will she cover up the length of the relationship to stop her sister finding out?
As regular EastEnders viewers will know, this isn't the first time Roxy has betrayed her sister like this.
She slept with Ronnie's ex-husband Jack Branning behind her back, resulting in her falling pregnant with daughter Amy.
Will Ronnie be as forgiving this time if she finds out? As we all know, secrets don't stay secret for very long in Albert Square…
