Biography[]
Mitch was the boyfriend of Blaire Lily, the best friend of Adam Sewell, and had also been friends with Ken Smith and Jess Felton.
On April 12, 2014, Mitch and Blaire had been flirting and sexting with each other over Skype, talking about their plans to lose their virginities to each other on prom night. Suddenly, however, they are joined by Jess, Ken and Adam, who claim they had received invites to the call, despite Mitch and Blaire having no memory of doing so. Shortly after, the group of friends notices an unknown user with the username "billie227" has also joined the call. They try to get rid of the intruder in various ways but are unsuccessful each time. Blaire looks up the account's username online and realizes that it was the same username as their ex-classmate Laura Barns, who had committed suicide the previous year as a result of cyberbullying she had received from a video of her passing out and defecating while intoxicated at an unsupervised party.
The group suspects that a classmate, Val Rommel, is pranking them, seeing as it is the one year anniversary of Laura's death. After they invite Val to their chat, Jess' Facebook page is suddenly updated with embarrassing photos of Val at a party. Jess denies uploading the photos and deletes them from her account, but the pictures instantly reappear on Adam's account. Val calls 911 to report that she is being harassed, then abruptly leaves the chat. Shortly after, the group receives a photo of Val and Laura's messages from before Laura's death, with Val telling Laura to kill herself. Val rejoins the chat, sitting still next to a bottle of bleach before collapsing. Police officers arrive shortly after, and they eavesdrop and deduce that Val died from a presumed suicide. Ken, a computing know-it-all, distributes a program to remove "billie227" from the chat, and Adam attempts to call the police. However, the 911 operator turns out to be the intruder, and "billie227" re-enters the chat, revealing a camera view from the other side of Ken's room. He approaches the camera source and his Skype is briefly cut before it shows him killing himself with a blender.
Laura forces the remaining four friends to play a game of Never Have I Ever, stating that the loser will die. Jess reveals she started a rumor that Blaire had an eating disorder, Blaire stole and crashed Jess' mother's car, Mitch had made out with Laura (and then threw her off since it was one-sided on her side) and reported Adam to the police for dealing cannabis, Jess stole $800 from Adam and Adam offered Laura to trade Jess' life for his. An angry and drunken Adam finally loses his temper and uses the game to force Blaire to reveal that she isn't actually a virgin, having slept with him twice behind Mitch's back. Mitch retaliates by forcing Adam to admit that he roofied a classmate, and then forced her to abort the resulting pregnancy. Blaire and Adam suddenly receive messages sent remotely to their printers which they refuse to show to Mitch and Jess. Mitch threatens to leave if Blaire does not show the note and Laura warns that Mitch will die if he signs off. In a moment of panic, Blaire shows her paper which states: "If you reveal this note, Adam will die." Adam shoots himself, revealing he had the same note, except it was for Blaire.
Laura continues the game, asking Jess if she defaced her grave. When Blaire convinces Jess not to continue playing, Laura cuts the lights in Jess' house and disconnects her video feed. Blaire looks for help on Chatroulette and has a stranger in Nevada send police to Jess' house. Soon after, however, Jess' Skype reconnects showing her being killed with an activated curling iron forced down her throat.

Mitch's death.
Laura then demands to know who uploaded the embarrassing video of her that made her take her own life. Despite Blaire having been the one to do so, she lies and says that it was Mitch. Laura promptly kills Mitch by possessing him and making him kill himself by slamming his face into a knife, which stabs him through the eye.
