Not sure why that was the scream they all heard. It's possible that, I can't remember everytime Lydia has screamed since they all seem to run together now, but it's possible this was the first time everyone was close enough to Lydia while she was screaming to be affected by it/

It was always a bit of a toss-up whether Jennifer would end up a villain or end up being a victim and die at the end of the season.
