"If 'that' didn't happen" (Spoilers)

[Warhammer]

Anyway: What if Littlefinger had been captured by the Sparrows when they sacked his brothel?

They'd break Littlefinger. Littlefinger would be severely delayed as if he was still in King's Landing, that would mean he wouldn't have killed Joffrey, which means he wouldn't have been in a position to kill Lysa Arryn or pair Sansa with the Boltons.

At least, I think.
