In the video of Vee on drama at Rotu at CBS web sit, she says that "Tammy wanted to talk to Gabriel about something that he said, and we noticed people going back and forth". Thus the CBS clue about an "innocent comment stirs activity".She also mentions, which I find interesting and sort of backs up Robert's comment, that "they don't know if there's a head in this group or if everybody's on an equal playing field or if people are forming little here and there."

If this was discussed in another thread, then lock this up as I didn't remember anyone commenting on it.
