The Walking Dead star Samantha Morton has hit back at claims her character's origin story was "inconsistent".

Tales of the Walking Dead fans got another Alpha origin story during Sunday's episode. However, some fans of the series claimed that the story contradicted a previous origin story that featured the character.

Fans were left questioning where Beta was considering Alpha's original origin story featured the character heavily.

Others also questioned why Alpha's head was shaved when she meets Beta before she’s become a Whisperer, but then not shaved when she meets the Whisperers for the first time.

Morton has hit back at suggestions that the writers made mistakes with the episode, and revealed that she was "heavily" involved in its development.

"There's no inconsistency at all. I was very heavily involved in the making of it, in the development of it with Channing [Powell] – there's no inconsistency," she told Digital Spy.

"I think that the episode is called Dee, and that says it all."

In The Walking Dead, Alpha led the Whisperers, a group of survivors who blend in by disguising themselves as zombies in order to go unnoticed – though Morton appeared to be playing a version of the character before she became Alpha in the anthology spin-off series.

According to the show's bosses, Alpha will be the only familiar face popping up in Tales of the Walking Dead.

"Everybody else is new and will be a new introduction to the world and to the audience," said series writer Channing Powell at Comic-Con in July.

"So you can have not watched The Walking Dead ever, or Fear the Walking Dead, and start this series knowing everything you need to know, really.

"And it was really fun, we got to create these characters in the writers' room and [the franchise's chief content officer Scott M Gimple] already had some ideas going into it, so everyone except Alpha is new."

The Walking Dead season 11 airs on AMC in the US and STAR on Disney+ in the UK. Tales of the Walking Dead premiered in the US on August 14, but currently has no UK release date
