Reiss’s grandfather’s brother was Bob Colwell, Dot’s father.
On joining the soap, Jonny Freeman said: “I am delighted to be joining the cast of EastEnders, especially as part of the iconic Dot Branning’s extended family.
“Everybody has been so welcoming and I'm very lucky to have been working so closely with the lovely Natalie Cassidy who is not only a fantastic actress but a delightful person; she has very kindly helped me navigate my first few weeks. I hope I can do Reiss justice.
“He is kind but socially awkward and seeing how he manages, or doesn't manage, his early exchanges with Sonia and her nearest and dearest has been quite interesting! I’m looking forward to seeing how both audiences and the residents of Walford respond to him.”
EastEnders airs on BBC One from Monday to Friday at 7.30pm.
