Alexander Rozhenko at 50:
[referring to young Alexander] I staged the assassination attempt to try and frighten him, to make him realize that he must follow the ways of the warrior. If I had listened to you, if I had become the warrior that you had wanted me to be... you would not have died in my arms.

Lieutenant Worf:
No. Who knows what the future will be, now that you have disrupted time. I may die tomorrow, or I may outlive you. But when I die, I would like an honorable death; and the only way that is possible is for you to accept yourself as you are, and stay true to what you believe.
