Talk:A is for Answers/@comment-3359877-20140307221849/@comment-24.45.12.126-20140307230350

according to the leaked script, A follows the girls onto the roof of a building. And Ezra shows up unexpectedly, in which he demands A to give up cause he "know who he/she is." and they begin fighting in the dark corner of the building. A escapes, but loses shim's gun. Aria talks to Ezra and when he turns around discovers he is shot and his fate is left unknown because he goes unconscious.

I'm pretty much assuming this is the way the producers hint that Ezria will be back on in season 5. They probably will forget about Riley like they did with some other characters.
