Itscassie

 Itscassie is a youtuber, who claims to be the Cassie mentioned by Bree(lonelygirl15).

 In her first video, she claims that she didn't contact Bree because she was scared.  She whispers because she claims that nighttime is the only time she has that is safe to make her videos.

 In her second, she thanks Bree for taking down the welcome video she posted so quickly.  It has been rumored that there was never a video posted as a welcome back for itscassie.  However, she also mentions that no one can know that they're connected.  Also in this video, it becomes extremely obvious that she's wearing a wig.  one thought of why is that she has reached the point where she must shave her head, though nothing of the sort has been confirmed.

 In her third video, itscassie says that she wants to prove to Bree that she really knows where Bree's parents are.  She says that she's going to go check on them.  She gets to the door, and opens it to go inside, but something goes wrong and she is heard gasping and saying "Oh my god."  Then, it seems that she is running and when she finally comes back into view, she says that she saw someone looking over them in the dark and that seh doesn't know what is going to happen now. She also says that this is very bad, and if she'd known that they were being watched over, she wouldn't have gone.   

 The itscassie videos have not been confirmed to be in any way related to LG15 and there is mass controversy on the subject.  

 The itscassie videos are extremely choppy, dark and mysterious.  We wait anxiously for the next.
