Gemmers19
Gemmers19 is a YouTube and Revver user who posted a video response to "Daniel, Be Careful" Gemma says that she knew Bree in England, when Bree was good friends with her dog. Bree mentions being friends with the dog in England in Mysteries of My Past... REVEALED!
Gemma also suggests that her parents are members of Bree's religion and this forced her to move to London. The editing style in Gemma's videos is similar to the editing in the lonelygirl15 videos.
The actress that plays Gemma has been identified as an aspiring actress named Jackie, who appears to be a friend of Jessica Lee Rose in real life. This connection has prompted many to speculate that Gemma is an official character. Bree, in her video "Hi Gemma!" responded to Gemma's video. This would appear to confirm that The Creators are incorporating her into the lonelygirl15 universe as an official character. On October 27th, Gemma's video was uploaded to revver by lonelygirl15: this confirms that Gemma is definitely part of the series.
Gemma's references to David Hume and Bree's mother's reaction to the discussions at the lecture she was attending may be significant.
