This episode starts off with a suicide which happened to not only be one of Natalie's friends but a Psychiatrist. Nick tries his best to comfort her but, more than ever, she feels the pointlessness of life rearing its head. Nick tries to talk her out of suicide even though he's tried it before and he tries desperately to make sure it all works out. She then tries to speed up Nick trying to gain his mortality via that "making love while feeding" plot point from "Human Factor" (and...you just HAD to resurrect my least favourite plot point of the entire series in the finale, didn't you?!). After seeing Tracy Vetter die, with her last words "you could've said something" (referring to his vampirism...and yes, that IS a plothole in this season) Nick accepts Natalie's offer and feeds to try and regain his mortality for her.
Lacroix has decided to leave town but before he leaves Nick tells him about the ideal of contemplating suicide. The episode actually starts off with this monologue he gives about how you shouldn't trade treasure for an empty box which is actually one of Nigel Bennett's best deliveries on this show. With that said, considering the last episode was a bloodbath of cast members and regulars on this show and the fact he...just killed a potential love interest he doesn't see the point. So guess what? The episode ends on a cliffhanger with Nick giving Lacroix a stake. So basically this episode ends with Nick most likely dying, Natalie dead, Nick's partner dead (AGAIN! But not like Lacroix) and the only survivors being the guy who died in the pilot story only to come back with no explanation and the police chief who, if this show had a season 4, would've been replaced anyway. So literally no one on this show hasn't died.
Okay, here is something the writers clearly didn't notice while making this, regardless of that Lacroix monologue, this may be the most pro-suicide thing I've ever seen! No, this episode actually does reflect on a LOT of the preceding episodes and how did the writers think it'd look when the overall message they wanted to leave the show on was "humanity is bullshit, you may as well kill yourself". It wouldn't be much if there was something else but considering this is the finale, its just a punch in the gut to everything that came before. The other thing has nothing to do with anything but...the episode before this involved Lacroix's master coming back and killing off vampires he knew one by one that was so powerful she was only able to be defeated via being so distracted with hurting Lacroix that Nick killed her, that really would've been a fitting end to this season in the long run.
Okay, onto the good, the acting is all top notch for this show, seeing some of the old episodes was a good way to get us invested in what happened, there were shocking turns as well as a mystery element to what Nick actually ends up deciding which, if I am to be honest, is a bit of a no win situation for these writers. If they decided to keep him a vampire for potential sequel series', we'd feel cheated that all of that was pointless, if they made him human...he's just a human being like everyone else. A Daywalker is probably the only justifiable means to an end but don't tell me how they'd do that.
Overall, this is a rather crummy way to end the show but its not awful. It certainly has its moments that make it satisfy in some areas but WILDLY dissatisfy in others. If your a fan I just say what I think on this.
