“The secret to Q was the Q and Picard relationship. Q was in love with Picard, for some reason. That was the underpinning of the relationship, which was why, when he came to Deep Space Nine, he wasn’t as effective a character. The weird love affair that he had going with Jean-Luc made that whole thing work, and it made ‘Tapestry’ work, and ultimately it made 'All Good Things…’ work.” – Ron Moore

Commander Riker, will you report to my Ready room?

Well, you may not trust me, but you do need me. You’re not prepared for what awaits you.

Doesn’t it taste good?

It’s two days before your unfortunate encounter with a Nausicaan sword. You have that long to make whatever changes you wish. If you can avoid getting stabbed through the heart this time, which I doubt, I will take you back to what you think of as the present. And you can go on with your life with a real heart.
