About the plotholes,
in S2 we found out that Alison actually figured out that Mona was A by tracking her to Brookhaven,
but in the finale
Alison didn't know it was Mona until she visited Hanna at the hospital.
What sense does that make?
Who did Ali meet at the fair by Hilton Head,
and are they just going to
ignore Duncan even existed.
And NNNNNNNNNNNNNNN @ the writers being so transparent while trying to blame Alison's behavior on her mother. They should really just stop making excuses for all the things she did. The DiLaurentis family scene was cute and all, but making Jessica all of a sudden a bad mother who pushed Alison to bully people is a plot hole as well. Are they forgetting the lunch scene where Alison forced her mother to give her permission to go fool around with college boys.
And not at Jessica randomly hating the girls when in S2 she wanted the girls to walk the fashion show, and in the beginning of S4, she was friendly with the girls. Why was she at Wilden's funeral in the first place???
Who is Black Widow? They promised it was S4 endgame, yet there's no promos, no mention of it. Another aborted arch that could of been good. Marlene King and the rest of her writers team that reek of mediocrity will be getting these hands on Twitter for all the MESS they've incorporated this show with
it's so annoying how they just ditch an arc without completing it 
but I'm almost sure they will end there and we'll end up not knowing who that person is until like S7.
