In trying to find Durant's image, Michael reviews the video of himself being shot and pauses on an angle of Durant's reflection in a briefcase. He then asks KITT to clean up the image to construct a picture of Durant. But only a few seconds earlier on the video, right after Michael pulls the beard off, Durant's face is clearly and cleanly visible straight up on the video.
Lighting was used in a shot of Michael and Stevie on the beach, given away by a faint tell-tale shadow behind them in addition to the darker shadow, at a different angle, from sun.
At the wedding, RC3 runs past Devon, who is just getting moving, yet when they come through a door, Devon has somehow passed RC3 and emerges first.
The footage of rockets firing at Michael and KITT in the warehouse showdown is recycled from previous episodes, including those with Goliath.
KITT: Where are we going, Michael?
Michael: (hesitating) We're going home, KITT. To family ... we're going to the Foundation.
(Michael is about to beat Durant to death)
KITT: Michael! Michael, stop it! You wouldn't be able to live with yourself!
Michael: I'm going after Durant on my own.
Devon: No, Michael, please! The Foundation is working in conjunction with every law enforcement agency in the country.
Michael: Well, then tell them to stay out of my way!
Devon: You can't do this! There is a judicial system!
Michael: I don't need a judge and jury for this one.
(Stevie and Michael are strolling along the beach, arm in arm)
Stevie: This is a little too perfect to be happening.
Michael: It's the way I always wanted it to be for us.
Stevie: There's a thing called reality, you know.
Michael: Not yet, Stevie. Oh, not yet.
Devon: Michael needs the will to live, a reason to care. And I've got to find that for him. Yes, he has a right to that even though FLAG may lose him.
(Michael has told Devon and Bonnie that he wants to quit FLAG)
RC3: You two look as if he's dead.
Bonnie: No, but he's not exactly alive either.
Michael: I'm not sure I wanna live out my life as Michael Knight anymore.
Devon: Oh, it won't be easy to leave, Michael. Believe me, I know. You've seen too much. You've witnessed the violence, the injustices. You've seen the good we can do. You've been part of it for too long just to walk away.
KITT (quietly) : Michael, are you feeling better?
Michael (confused) : KITT? Where are you, buddy?
KITT: In the parking lot, Michael.
Michael (smiling) : How long have you been there?
KITT: Since they brought you here nine days ago. You have no idea how many baby carriages and wheelchairs have bumped into me. So, if for no other reason, other than my dignity, please get out of that hospital bed!
Michael: Soon, pal, soon.
KITT: Michael, we both know you're strong enough to leave now. If you're going through an emotional crisis, having trouble resuming your life again, I may not be able to solve it, but I'm ready to listen.
Michael: Problem is, I don't know what life I wanna resume again ... if any.
Devon: [Durant] was licensed to kill by both sides. (grim) I think he enjoyed that.
Stevie: You may break, you may shatter the vase, but the scent of the roses will hang 'round it still. The scent of the roses will remain forever.
Music: "As Time Goes By" (instrumental); "White Bird" by It's a Beautiful Day; Bridal Chorus by Richard Wagner; The Carpenters' "For All We Know" sung by Catherine Hickland.
This was originally intended to be the season four finale, and a possible series finale, but "Voodoo Knight" replaced it, this episode is wildly accepted by most Knight Rider fans as being the "real final episode", as it gave Michael Knight's story arc of finding an identity in life a decent, gratifying conclusion. When the series airs in other countries, this episode sometimes airs last.
The title, and Stevie's last line, come from a poem by Thomas Moore entitled "Farewell! But Whenever You Welcome The Hour", which is relevant to this episode as it encourages one to keep their happy memories close to their heart, even when times are cheerless and heartbreaking, just as Michael chooses to remember Stevie.
