Setsuna is Sailor Pluto, the lonely guardian of Time. I think she has some stuffy old boss named Chronos...the king of time, so I've heard. Her job is to stand around guarding the gates of time all day... So who can blame her for coming to Earth to get away from it? (Boy, the vacation days she must have stockpiled... it boggles the mind...)
Setsuna has the third Talisman or whatever you want to call it. She also figures out how to get them without killing anyone, luckily for Haruka and Micheru, who were the other two and would have left anyone with a talisman to die. The rest of the season, she hangs out with H and M, I have no clue why... Some "Outer Soldiers have to stick together thing", maybe... But then they try to kill Saturn... Honestly...What do they think she IS, a ROCK?
Then, Pluto stops time to save Haruka and Micheru... I'm sure a comment about wondering why would be in bad taste...so I'll say it anyway... WHY?! Well, she would've died too... Ah well.
Also, in SMR, Pluto was Rini's friend. Rini often talked to her through the Luna Ball (Luna-P, right?). Also, Setsuna gave her the Time Key, so that Rini could travel through time pretty much whenever she wanted.
Honestly, I broke a lamp on the ceiling when I heard they changed Setsuna to Trista!... Er, don't ask... Eh heh... I better wrap this up now... ^^;
