Who should Sirius have been romantically involved with?

REMUS LUPIN

Oh, come on. He "embraced Black like a brother"? Sure. "Brothers". Let's go with that.

Come on, the fanfic writers know it! ;)

i thought sirius and Tonks would and should have dated Tonks when i read book 5 but lupin & Tonks r so cute 2gether i dont think so anymore.

I could see Sirius with Tonks if he had never gone crazy and been in Azkaban. But of course, Tonks and Lupin were an inseperable couple that was meant to be. R.I.P.

i know its kinda gross, her being related to him and all, but personally, i've always loved the idea of him and bellatrix...

even though he's sane, and she's insane...
i've always liked the idea....
light and dark, just like dramione...
I also ship that....

Bellatrix :3
