Fans have all speculated that Tyler was heading for a school shooting, as a result of being so heavily bullied and isolated from other students throughout the series.
Seventeen.com spoke to Devin, and he revealed some interesting things about a possible second season.
"I think that we have an incredibly talented writing team and they've done a great job of telling Hannah's story," he said after being asked if he believes there will be another season.
"They fleshed the characters out and made them three dimensional and realistic. All the plot lines they wove in worked out perfectly and are natural. So I think that we have great story lines that we could tell going forward."
Although the dark road Tyler takes wasn't so much of a shock to fans, it was for Devin at first.
"When I first read that Tyler bought a gun, I immediately freaked out because I was just so surprised. But when I read it again it wasn't so surprising. This is actually a perfectly natural place for his character to go after everything he's been through. I even saw some people on Twitter that were like 'Oh, I called this for Tyler's character since episode three.' So this isn't a magical dream possibility. This is something that people can see as a natural place for him to go to."
Aside from the obvious - that Tyler was bullied and pushed around by his classmates - Devin revealed a particular scene from episode 12 which points towards more of his plot line in season 2.
"There's a scene with Marcus and Courtney where he's like, 'I know a lot more than just what's on the tapes. I see everything. I have pictures of everything.' And Marcus is like, 'What are you talking about?' and Tyler says something along the lines of, 'What have you done around here that you don't want anyone to know about? I take a lot of pictures.'"
"It implies that Tyler know more dark things that people are trying to cover up that weren't on the tapes," he continued.
To think that there could be worse things that went down at Liberty High from what we heard from the tapes is INSANE! If it involves Bryce, so help us gaawwd.
So clearly, there is a lot that producers could go on for a season 2, but it's important to remember that the show was created to spread a message that goes beyond being a successful television show, and Devin agrees with that.
"The first season came with such an important message and story. We really talked about sexual assault, mental illness, and made it for the people who really need it to relate to and have that validation if they need it. At the end of the day, we can't just put something out there just to keep it going. It has to be important and it has to be for the people who need it - by telling an important story and continuing on the track of mental illness and maybe going off to explore more about gun safety. So if we approach it with the same thought, care, and love that we did the first season, then I think it could be something really great."
Don't we all Devin, don't we all.
"It would be done that way if we continued," Devin said. "We wouldn't do it any other way."
