Last year was difficult for Mrs Branning as her dear friend and former resident of Albert Square Dr Harold Legg (Leonard Fenton) died.
She later found out he had left everything to her in his will and was now incredibly wealthy.
But while everyone else celebrated, Dot contemplated what had happened and her future.
She informed Sonia: “I’ve made up my mind. I’ve decided I’m going to go to Ireland and stay with my grandson Charlie and his family.”
The official EastEnders Twitter account added even more fuel to the fire tweeting: “It’s time for Dot to move on. And we couldn’t be sorrier to see her go.”
This sounded like a permanent exit at the time but has since called it just a visit to spend time with her family.
So is this the last time viewers will see Dot after three decades on EastEnders?
Eastenders continues tomorrow, Thursday, January 23, at 7.30pm on BBC One.
