"At least one scene comes to mind that's gorier and scarier than anything we had in season one," she told the publication.
"Joe is new to Los Angeles fully intending to start over a new leaf and never being forced to do bad things again."
"Episode two of the season has my single favourite shot that I have been a part of in my entire career.
"My career is full of blood and gore and monsters. It's also beautifully shot and the director who shot the second episode lavished a lot of love. Joe is forced to do something he really doesn't want to do.
"Joe is always trying to be a good guy but yet somehow he's finding himself in these thriller, horror kind of situations. It's terrible for him but I think it's going to be so much fun for the audience."
Knowing Joe, that could be anything.
The last time Joe let his emotions get the better of him, he ended up murdering the love of his life Guinevere Beck (Elizabeth Lail). So what does his future with new love interest Love Quinn (Victoria Pedretti) look like?
"Love is very different from Beck," Sera revealed.
"We were aware going into season two of the show, there was something very special about Beck the way that we told it in season one.
"We knew that it wouldn't be possible to repeat it as the audience is very much onto Joe now and will see through him. The way that Love enters his life is very different. His interest in her and his expectation is also very different. I think it will be fun and interesting."
We are eternally frightened.
You season two will land on Netflix on 26 December!
