So after visiting rapist Lee at work this week, next week sees Robert take his revenge plan even further - and Victoria's less than impressed.
After asking Robert to just let her get on with her life, as well as revealing she's keeping her baby, Victoria has struggled because her brother's found it very difficult to give her the support she needs.
But whether he does or not, it seems they feel there's more to be done and decide to step up their game next week.
Heading off very early in the morning with a plan, they eventually sneak home pleased that they've successfully managed to fly-poster the garage where Lee works with pictures of him emblazoned with the word "rapist".
Victoria is fuming when she discovers the posters and lays into her brother for betraying her trust and not leaving well enough alone.
When the police then get involved, Vic reacts even worse and insists she wants nothing more to do with Robert.
Aaron resolves to make things up between them, but can he bring the siblings back together? Or is this one step too far for Victoria to forgive?
Last month viewers were outraged when Robert appeared to blame Victoria for her rape, insisting he would have made sure she'd gone to the police sooner had he known about the rape, and also claiming he wouldn't have let Lee into the house in her shoes.
Robert also reacted badly when Vic said she wanted to keep her baby.
Could this latest betrayal spell the end of their brother/sister bond for good?
Emmerdale is on Monday to Friday at 7pm with extra episodes on Tuesday and Thursday at 8pm on ITV.
