Q: Did Derek really kill Jesse?
A1: Unclear at this time.
The last shot before commercial break was of the trigger being pulled,
and it is unlikely that Derek, a soldier from the future and a present day fugitive, would have an empty gun
(he don't like firing a weapon unless he loaded it himself as he said in "The Demon Hand").
Derek told John that John Connor let her go, but did not say if he himself did.
