Warning: spoilers. Also, slightly simplified for ease and communication.
When we first see her, Marius asks Eponine to find his new love, Cosette. Having never known love before, he challenges Love Is For Other Men d6, rolling 3d6 and adds his Relationship, Eponine Is My Greatest Friend in the Whole World d10. Eponine resists with Justice (Thems That Are Rich Deserve Nothing) d8 and her relationship with Marius which is Marius Will Be Mine d12. Eponine has dice on her side but Marius is dead keen and spends a Plot Point to also roll his new relationship Cosette Is The Most Beauteous Creature on Earth d6 and it gets him over the line. Eponine, not wanting stress, runs off to find the girl.
Later, Eponine sees her father trying to steal from Jean Valjean, having realised he can’t go to the police. Threnadier tells her to shut her mouth, she resists. Thernadier rolls Power (Master of My House) d10 and Eponine Will Do As She’s Told d6. Eponine challenges her Duty (Family Is All I Got) so she can roll 3d6 AND challenges her relationship Marius Will Be Mine so she rolls 3d12. Not surprisingly, she gets a titanic success and drives her father away. She drops both her Duty and her Marius stat down by one for the rest of the episode. At the end of the session, she rewrites that to Marius Deserves Happiness Even If That Is Without Me so she can keep it at d12.
Next Act, she finds the letter from Cosette. Even though the two never interact, the GM makes it a contest. Cosette rolls her Love d12 and her budding Marius Is My True Love stat (d8 they only just met), but Eponine rolls Truth (Everyone Lies) d12 and challenges Marius Deserves Some Happiness, rolling 3d12. She wins again and hides the letter. Because she challenged it, it drops, but at session end she changes it back to Marius Will Be Mine, so she can STILL keep it at d12.
Next session, on the barricades, seeing Marius about the be shot. Marius and Eponine challenge each other. Marius rolls Duty (I Must Suffer To Balance Out My Noble Birth) d10 and Eponine is My Best Friend In the World d10 to take the bullet. Eponine rolls Love (Is All That Matters In the End) d10 and challenges Marius Will Be Mine once more, rolling 3d12. She wins once more, and totally totally dies. Marius gives in and hands her the plot point, but she hands it back and deals him stress instead (d12 Anguish).
But she is clever. As she dies, she sings A Little Fall of Rain, relieving Marius’ stress, so he has in fact lost nothing. Eponine is a motherfucking powergamer. But nobody gives a damn because in Smallville, powergaming = drama.

That’s awesome. Now we just need a version of Cortex Plus Drama with rules for musicals!
Just another reason we desperately need Hackers’ Guide: Volume 2…
I’m using Smallville to run a musical right now, in the play-by-post forums on rpg.net. 🙂
A very nice illustration, thanks. Given Smallville literally arrived for me in the post today it put a lot into perspective. (I’m neonchameleon on rpg.net).
Awesome! Let me know what you think and do with it, and ask me any questions!
I have no idea yet 🙂 I picked it up because I’m running both other Cortex Plus games and they’ve both been an absolute blast. I think I need to re-read it and draw out a relationship map to actually understand the game. Plus preferably play it to understand how wedges work.
Well, if you poke around this blog you’ll find lots of stuff that might help. Including the many relationship maps we’ve produced.
The relationship maps I get (although I want to use from the PC side before even trying to play Watchtower). The part I don’t conceptually grasp are the Wedges – does this section just mean “Make sure everyone gets some plot focus in the planned episode”?
Also if I ever run it, is it possible to simply cut the stress pool and use MHRP style effect dice? Or are two dice rolls just too common?
That’s what it means, but if you don’t do it with wedging, it won’t work. Because plot focus doesn’t mean what it does in other games, because plot is different here. You could use MHRP effect dice, I think that would work okay.
