Speaking on This Morning, Ross said that he is continuing to film more scenes following the aftermath of Peggy Mitchell's death.
Explaining that he was persuaded back to the soap by Dame Barbara Windsor as part of her exit storyline as Peggy, Ross said: "She's been a loyal servant for many years and started going back and forth and I think she wanted to do a service to the fans and the people who love the show as she loves it, to leave with a good storyline. Who can say no to Dame Barbara Windsor? Not me."
Ross had documented his return to the soap, sharing photos with fans as he learnt his script and stepped back on to Albert Square.
"It was great to work with Steve McFadden again, who plays Phil, and with Letitia Dean, who plays Sharon," said Ross. "First scene, first morning, three days in after coming straight back from Mozambique, jet lagged, really scared, really nervous.
"Because when I first joined it, 20 years ago, there was no expectation and of course as you get older there is more expectation placed upon your shoulders and I didn't want to let people down, particularly Barbara.
Ross added: "But I enjoyed the time that I was there and I'm going back again for a little spell. It was emotional in many ways going back to that square where I spent 10 years of my life."
For Extreme World star Ross, he's had a busy start to the year, and he reckons it might catch up with him by the summer: "I've had a tough year, started off in Columbia then went to Iraq and Syria, then went to Mozambique, just come back from Mongolia and I'm off on my travels again very soon.
"To sandwich that between Walford I thought was a bridge too far and I haven't finished it yet cause I've got to go back for another three weeks to finish off the storyline after Barbara leaves. So it's been an interesting year - I think I'll be in therapy by the summer!"
