BUT, oh yeah, now I remember him talking about Kiera being a good cop thingy, so maybe he did do that on purpose. I wonder if future Alec who did all that stuff remembers how badly Kiera wanted to go home, and how she dove after the time travel thing instead of staying with Emily? OR maybe old Alec realizes that Emily stood up and threw the thing when there were guns pointed at her, and probably there was nothing Kiera could have done to stop the bullet, even though she can make a force field with her suit.
