A doesn't shoot and miss.
That ominous statement from Caleb is in reaction to Toby and Jenna losing their home in a massive explosion announcing A is back in action.
Is the return of A related to Mona's Army? Who knows?!
From the following preview, it seems pretty clear we can rule out Ali having anything to do with A's return. Everyone is running scared, and in Pretty Little Liars Season 5 Episode 6 Ali wants to run again.
Given what happened with Shana, the girls are going to be more frightened than ever of Big Bad A. Did A return to take down Ali once and for all or will Aria come under fire, as well?
Watch the promo, worry a lot about the Liars and be back here on Tuesday for a full review of the episode.
