HIT show 13 Reasons Why returned to Netflix in August following the huge success of the first two series.
But is Hannah Baker still in the show? And what about Bryce Walker? Here's EVERYTHING you need to know about the third instalment of the very popular series...
Are Hannah Baker and Bryce Walker in season 3 of 13 Reasons Why?
Both Hannah and Bryce played central characters in the first two seasons, with the latter being one of the main reasons why Hannah killed herself.
But there is much speculation that neither of them will be in season three.
Hannah Baker
Hannah is NOT in the third series.
Actress Katherine Langford is not listed anywhere as being in season three.
Hannah's story has well and truly come to an end - with her committing suicide in the first series.
Her character appeared throughout season two as the storyline covered the aftermath of her death.
Following the trailer's release we knew that season three would be a 'who killed Bryce Walker' mystery.
Bryce Walker
The last time we saw Bryce Walker in season two, he was alive and well.
However since the trailer dropped it is clear to fans that someone has bumped off the evil rapist - but who was it?
The third series sees the students of Liberty High club together to figure out who is behind Bryce's death and also how he dies - so actor Justin Prentice IS in season three.
And of course - **spoiler alert** - it transpired to be Alex behind his death - after beating him up and leaving him with a broken leg and then ultimately throwing him in the water.
Who is in the cast of 13 Reasons Why season 3?
The show will see many of the characters from season one and two return.
The main cast includes:
Dylan Minnette as Clay Jenson
Dylan plays shy high school student, Clay Jenson, who receives a mysterious package in the post containing seven of the cassette tapes recorded by Hannah.
The 22-year-old is perhaps best known for his role in creepy (but critically acclaimed) horror flick Don't Breathe.
But he also played another character called Clay for three years until 2010 in TV series Saving Grace.
Dylan has starred in Scandal, Goosebumps, Agents of S.H.I.E.L.D. and R.L. Stine's The Haunting Hour.
Christian Navarro as Tony Padilla
Christian, plays Tony Padilla, the person Hannah gave her 13 tapes to in season one - each giving a reason as to why she made the decision to end her own life.
Before 13 Reasons Why, Christian also appeared in TV series Vinyl and The Affair.
Alisha Boe as Jessica Davis
Alisha dropped out of high school to pursue a career in acting and made her debut in the industry in 2008 as Lisa Swan in the horror film Amusement.
She also portrayed Laci in He's On My Mind in 2009, Tara in Paranormal Activity 4 in 2012, Tracy McCoy in Modern Family in 2014 and Brynn Hendry in Extant.
The star was the first actress with Somali origin to hold a leading role in an American film since fashion model Iman.
Brandon Flynn as Justin Foley
Brandon's big break came when he starred in the first series of 13 Reasons Why as the troubled Justin.
He's also known for his high-profile former romance with Sam Smith.
Brandon has had roles in Home Movies and BrainDead.
Devin Druid as Tyler Down
Devin saw his character suffer a horrific rape and almost shoot up his high school in season two.
Fans will be keen to see how his character moves on from this in season three.
Devin has had many TV roles, including starring in House of Cards.
