The Plague - S2-E6
Audio problem: When Bishop Brennan calls for the first time at the start of the episode, Ted panics and pretends to be French before hanging up the phone. You can still hear Bishop Brennan talking on the other end of the line for a few moments after Ted hangs up, which obviously shouldn't be possible.
Audio problem: When Xena says "It seems so haphazard" the word haphazard is said with her Kiwi accent. (00:29:30)
