I really think if they were bringing Serena in to play Robert's daughter they would have gone for a younger actress, someone more like Izzy who looked younger than they actually are in real life. Absolutely no offense to the actress playing Serena but there is no way she could pass for 20-25 imo maybe late 20's but her and Ryan on screen together could pass as the same age, given that Ryan looks younger than he actually is in real life. This is no shade to her I'm 30 myself and there is absolutely no way I could pass for 20/25 either!. I guess we wont have long to wait to find out though.
Plenty of people in their late 20’s play teenagers in soaps, so her being 30 playing someone younger isn’t anything new or surprising. I don’t think she is Robert’s, I just think there’d be more drama there because bringing in a random other relative seems like a strange choice not as if she could blame Robert for why she’s not been around the family. But also, a photo doesn’t do justice for some people I’ve never seen her in anything so I can’t comment but some people look a lot younger than photos. When you look at past people who’ve come in it made sense. Like Joe did, he blamed Charity for his Dad’s death so the drama came from that and it made sense, same with Caleb. Cain stopped him years ago being part of the family, same with Nate he didn’t know Cain didn’t know he existed but because he thought he did he wanted revenge, and with Lewis he had a sibling in the village and also a way for him to find out about Emma’s death. Serena coming in without any siblings in the village, no parents, and just a random like cousin I don’t see where the drama could lie there.
