That is just what I think bởi the way he acts and how old he looks. No logic to it but after thinking a bit and watching thêm I realized that he was probably 18-19. Arthur 20-21 Gwen 19-20 and Morgana 22-23hơn một năm qua
Merlin can’t be 21 because his father only met his mother after having to leave Camilo the because of the great purge and season one starts exactly 20 years after the great purge. Plus before going to Ealdor merlins father probably moved around a lot and then he probably stayed in Ealdor for quite a while before Merlin was conceived and Merlin was only conceived right before his father moved again as he did not know about Merlin and then it would of been 9 months before Merlin was born. So if Arthur turned 21 in one of the first few episodes( just after the 20th anniversary of the great purge) and Merlin was born a few years after the purge then he would only be about 17-18 in season one.
