While Ezra gasps for his last breath in the hospital, and "A" sneaks around behind him, the other big mystery Pretty Little LIars fans are excited about is: what is the dysfunctional Hastings family hiding? Will that be the big reveal of season five?

Ezra Knows Who 'A' Is?!

The Hastings family is currently under investigation because of Mrs. DiLaurentis, as reported by Wetpaint on May 2. Mrs. DiLaurentis buried her daughter Alison, then recently was buried herself.

One thing is for sure, dysfunction is all up in the Hastings family. Melissa Hastings told her dad who really killed the girl in Ali's grave. Daddy Peter thought it was his daughter Spencer who had killed the girl in the grave. It's quite likely that season five will focus on solving this shrouded mystery. It is unclear whether this little secret will stay between Peter and Melissa, or if they will involve Victoria. Also, what does Spencer know about it all?

Showrunner Marlene King previously told E! News, "I think there will definitely be a big reveal in the 100th episode -- it's going to be an emotionally epic episode."

Director Norman Buckley Instagrammed a sneak peek of the Hastings family from set of the 100th episode, with the caption, "Hastings, Hastings and Hastings. Hastings family dysfunction. #Myfavoritestoryline #Spinoff." The photo shows mom Victoria Hastings (Lesley Fera), Peter Hastings (Nolan North) and Spencer Hastings (Trojan Bellisario). There could definitely be a juicy spinoff in the future.

The cast and crew are currently shooting episode 100, Miss Me x 100 - which they tweeted photos all over social media.

Shhh... PPL 100th Episode Secrets!
