I think they did. Honest to gods, when the guy started attacking Jessica I screamed "YESSS!!!" at my TV. I thought that was the moment that's bring Trish into action and that she'd kick the guy's ass to protect her sister. But nope, no, she cowered in fear and waited for DD to come save them. I mean... really?

These showrunners are kings of plot holes. I thought they'd get better after DD s2 but they haven't.
