Draco *is* the most popular intrusion into snarry. I prefer Lucius to him, though not in snarry. ;) Lucius/James are so arrogant it's a wonder they *didn't* marry each other. :D The rare threesome in snarry is SS/HP/LL, even though SS/LL is just hillarious (Snape's jaw drops *often* when Luna is around), and b/c Luna is just as much an outcast as Harry and Snape, just took her own way to become one, she makes a strange sort of complement to Harry and Snape. I know of about *2* fanfics that have SS/HP/LL, and one of the fanfics is mine. The other is swtalmnd's, and of course I cannot remember what it is called^^. Hers is better. :P
