Peter fled to New Zealand with his pregnant girlfriend following the revelation that his little brother killed their sister.
But Ben Hardy, who plays Peter, has teased this may not be the last we see of him.
New mum Jacqueline Jossa [Lauren] tweeted: “Loved working with @benhardy0291 was a pleasure to leave with him @bbceastenders I will miss you!”
Ben replied: “Ditto! Miss you. Maybe one day Peter will come back to visit Lauren and Pete Jr (that better be his name)”
Fans will know that Jacqueline, 22, recently went on maternity leave after giving birth to baby girl Ella.
Ben’s reply certainly suggest Lauren and the baby will be returning to Albert Square without Peter, and Jacqueline previously insisted she does intend to go back to work after her leave.
Last year Jacqueline told the Mail Online: “I know I will be coming back. I read somewhere I was taking a year out which isn’t true. I definitely want to come back.”
But speaking to OK! magazine after the birth earlier this month, she said: “I haven’t really thought about it, I can’t really imagine working at the moment. But I love my job, so I’m lucky.”
Are you hoping Lauren and Peter return to the Square one day?
