Hannah Baker's mum, Olivia Baker (played by Kate Walsh) will continue to be part of the show, and has revealed to People Now the role she will be playing.
The end of season one, Tony gives Hannah's parents a copy of the tapes in MP3 format for them to listen to, which would help them with their court case.
"We'll see more and more of the mystery getting revealed, and I think you see Mrs. Baker still questing for the answers of what happened to her daughter," she began.
"We've already started shooting, so I know here it's going."
Kate also revealed what creator Brian Yorkey will be adding...
"His use of time and going back and forth in time, we'll see more of that. He has such an incredibly all-encompassing vision for the show.
"He does a great job of playing with storytelling in a kind of Rashomon kind of way, so you see it from lots of different points of views."
It will be interesting to see the show not dictated by Hannah Baker, although she too will be returning for flashbacks.
