Two of the last two statues Demona destroys with her laser rifle appear to be recurring characters Brendan and Margot. Margot and Demona are both voiced by Marina Sirtis. However, due to fan outrage that these two would be killed, they reappear later in the series and Greg Weissman confirms that the victims here are simply lookalikes.
This episode takes place in 1032 and 1995.
There were a few people who were smart enough not to keep watching Demona's broadcast; having looked away or turned off their TV. Obviously something would be off if a spooky looking woman hacked into the public broadcast.
