For House/Foreman slash, there's nothing like a good long look at Poison, DNR, and Distractions. Detox, too. Foreman takes care of House when he's sick; House is so totally jealous of Foreman's old boss, Marty; and they're more alike than either of them wants to admit. Plus, the end of season three? Come on! House didn't want Foreman to go! He practically begged him to stay, even if he did it poorly. And Foreman's "I don't want to be like you" speeches? Nothing but repressing his own desires, man.
And,
Sans Serif, the plotbunny Dee gave me will eventually be a sequel to my last House/Foreman piece,
Percussion. I'm writing more in that verse as we speak.
