What can I say? This is the arc when I literally shouted to the tv screen "T'Pol, kill them all!" You know, after this three episodes I was a total fan of the poor girl. I mean, I always wondered why T'Pol was so passive-agressive and why she was always seeking to be galactically miserable (her characterization this way was very constant.) But after knowing her mother (and Koss), I could completely understand. When your loved ones treat you like they give a shit about you and you were five years old, it can disturb you a little.
And the Vulcan arc just make it worse. Let's see...
KOSS: Hi, hon. I'm here with irritating and unwanted gestures of affection and puppy eyes, after blackmailing you and force you --because I didn't have enough personality and backbone to do otherwise-- to marry me, just to tell you that... ha! This is funny! Your mother is part of a dangerous fanatical cult. Congratulations!
T'POL: That's all?
KOSS: Mmmm... Oh, yes, take this family heirloom that you've never seen. Want a quickie?
T'POL: No.
So she has to go to Vulcan with Super!Archer, who knows nothing about Surak (although T'Pol gave him a book of him...
two years ago!), knows nothing about Vulcan phisiology (helloooo... Vulcans have evolved there!), but manages to criticize Vulcan pets. She encounters a Vulcan Syrranite that preaches a lot and slams her (because belittling T'Pol is a national sport on Vulcan.) He dies (we open the champagne) and T'Pol reaches the Syrranites at last. And her mommy. And her mommy's reaction is memorable:
T'LES: Oh, don't put that face. Yes, I know I ruined your life for, you know,
nothing, without consulting you at all, since I treat you like you're five, but do you want to join our little gang?
T'POL: Your gang is a fanatical and terrorist group.
T'LES: Oh, that's not true. We would never kill anybody, we just ruin people's life, but that's absolutely fair.
T'POL: Oh, paint me sceptic. Because I'd want to believe you, but I find it difficult after you lied to me so blatantly when you told me
you didn't take restricted data from the Academy archives.
T'LES: Crybaby.
Then we discover that Super!Archer has SuperIrish!Surak's katra inside. Yeah...

So T'Pau decides to perform some obscure and very dangerous Vucan procedure, even against his will, to extract it. T'Les (reluctlantly, that's true) agrees, because T'Pau is her lesbian lover, after all. I mean, it's obvious. It's that or T'Pau is the daughter T'Les always wanted and never had. Anyway, the Vulcan mojo doesn't work, of course, and while T'Pol is taking care of Archer (although she shouldn't, because he's quite an ass), T'Les comes to talk to her.
T'LES: I don't know why you're so angry. It's totally un-Vulcan.
T'POL: Maybe because you forced somebody to go through a mind meld. Which is very similar to a mind rape. A concept I loathe since I went through one. You know, the mere memory makes me retch.
T'LES: You never told me.
T'POL: Of course not! We are not even remotely close and you never ask me
how I feel or how I'm doing!
T'LES: You're too emotional. Besides, the mind meld was necessary. We say it was necessary and that makes it right, because we're right and anything we do is right.
T'POL: You know what, Mace Windu? I don't want to talk to you again.
So... Super!Archer discover where the Kir'shara is, because SuperIrish!Surak never told anybody except him where it was. Oh, the sly dog. They recover the old artifact, but when they return the camp is destroyed and Mommy!T'Les is dying. Dying, but not dead, so she has energy enough to talk.
T'LES: Let me tell you, while I have stil my breath, that
everything is your fault. Yes, because if you were a good daughter, I wouldn't come here to try to
cure you. But you're too emotional, so I had to try to lead you toward the right path and when that didn't work, I came here to find a solution to your desire to have a personality. And now the High Command has bombed this place and I'm dying. Have I told you that's your fault?
T'POL: Yes, Anakin Skywalker.
T'LES: Good. Now that I've planted the seed of eternal guilt in you, let's end more cheerfully. I'm proud of you.
T'POL: (flabbergasted) Really?
T'LES: Yes, I know I've never shown you it. In fact, the 90% of our interaction was based in arguing, but in the deepest part of my katra, I was proud. I simply picked on you in public for my image's shake. OK, now I've said what I wanted, I can die in peace. But remember, this is all your fault.
After that, the situation just worsens. T'Pau takes the opportunity to remind T'Pol that she had a better relationship with T'Les than her own daughter. But that's understable, T'Pau was her lover. And later, Super!Archer tells T'Pol
how to be a proper Vulcan!
I don't know how she didn't shoot them to death.
Anyway, after all of this ends. T'Pol receives the lovely visit of the lovely Koss again.
KOSS: You know, I'll end our marriage. Yes, now that your mother is dead, I have no argument to force you. I know this would be the perfect moment to tell you that, in fact, my parents or myself -pick an option- are/am Syrranite(s) and that the marriage thing was a plan to make you safe. Although nobody told you anything because we treat you like a five years old child and telling you this would give you the opportunity to, for Surak's shake, choose. But I won't tell you anything, and I'm going to give you the impression that I'm a dense and cruel blackmailer (although it's impossible to be cruel being dense) because that's how I am. I'm going to act as if I give a shit about the entire situation, and you, especifically. That would be perfect. Oh, yes. Goodbye!
I'm not surprised that T'Pol had to reconsider all her life and belief system in "Daedalus".
Sorry, I'm cranky today
