When Caleb asked Ezra to help him locate the game???
<b><p></b> <b>Caleb:</b> Hey Ezra want to help me find this thing you don't know about?<p/><b>Ezra:</b> Sure thing, ex-student! I'll get Aria.<p/><b>Caleb:</b> *coughs* No, sorry... We all hate Aria now. Can YOU just come and help US?<p/><b>Ezra:</b> Oh, okay. Sounds good!<p/></p><p/></p>
The way they showed it made me think that the bullet wound is going to be how we can differentiate between Spencer and her twin.. And now that we know Jenna didn’t shoot Spencer, since it wasn’t her gun, and Mary probably didn’t either (she’s had opportunities to kill her since then and she hasn’t) I honestly think that maybe the writers are paying homage to the book and the twin wanted Spencer dead so she could take her life. But when her twin failed she started the end game.
