Archie - played by 65-year-old Larry Lamb - was last seen leaving Walford on Friday night after nephew-come-stepson Phil Mitchell (Steve McFadden) failed to kill him, despite the direct order from his mother Peggy (Barbara Windsor).
At the beginning of the month, Archie's world caved in on him as his lies, manipulation and deceit were finally revealed on his wedding day, which resulted in the controversial death of Ronnie's (Samantha Janus) biological daughter, Danielle Jones (Lauren Crace).
Following his family's complete abandonment of him - including his daughters Ronnie and once-besotted golden girl Roxy (Rita Simons) - Archie turned to Danielle's killer Janine (Charlie Brooks) for a roof over his head. Deciding to leave Walford, Archie walked to the tube station, only to be bundled into the back of an unmarked van.
After having his stepfather kidnapped, Phil had him bound and blindfolded in the Arches where he threatened to end his life. However, Phil quickly realised that Archie would suffer more if he were forced to live alone as an outcast from his own family.
Despite his disappearance, however, Phil hadn't bargained for Archie to be plotting his comeback so soon.
An EastEnders insider said: "Who knows how Archie will return to Walford? He left a lonely, broken man who had lost his whole family due to his cruel lies and manipulation. He walked away leaving a path of devastation for the Mitchells which will be felt around the Square for many weeks to come."
They added: "Will he come back a reformed character desperate to rebuild his family again? Or will he cause yet more upset and mayhem for the Mitchells?"
Larry Lamb returns to filming within the next few months, and will make his screen reappearance in the summer.
