And then someone sheds their...
"Chrysalis"
I see the blurb and I wince. The most annoying guest characters I can remember (and that's saying a lot) are back.
I will digress here and say they remind of some character types from some of the darker corners of Trek BBS. You've got the manic guy with delusions of grandeur and an unshakable sense of his own superiority; the attention-seeking histrionic woman; the nice but easily upset guy; and the cataleptic woman. Well, the last one wouldn't be on here, but you get the point (I hope). I can really picture Jack posting huge walls of text arguing minor points of continuity.
But anyway, they want to make Sarina normal, and it's up to Bashir to do it in 45 minutes, otherwise she's condemned to live in a cataleptic state her whole life.
And, thanks to the machine the Jack Pack improved, he's able to do it, although for some reason none of them can use the machine to help themselves, or design a machine that would do so. And since their problems can't be solved in 45 minutes, they make no effort to solve them.
Then Sarina comes out of her state, and she can talk, but Jack makes fun of her, so they start singing. I can appreciate that the song sequence was a lot of work to put together, but I just wasn't into it, probably because I don't really like the Jack Pack much.
When we see that some level of neurosomethings is high, I guess that Sarina's going to go "Flowers for Algernon." That turns out to be wrong.
Bashir falls in love with her. She's incapable of reciprocating, and since it's the fifth act and she's not a recurring character, the solution is for her to move far, far away. When she asks Bashir if he'll remember her, I half expect him to say, "Nah. I've only got a few more months here, then I'm going to try to get movie work."
The quality seems to have dipped a bit.
