[MAIN SPOILERS] Haven't heard anyone bring this up before..

This may be a little bit of a stretch but I'm in the middle of re-watching the series again and I had an interesting thought. In one of the very first episodes we meet Ros (the red head girl throne was with) and at the end of the episode she rides off in a cart to Kings Landing.

Now it may be because there are so many explicit sex scenes that tend to involve women of the worlds oldest profession, but I never noticed how many pivotal scenes that Ros is in. She is there when the gold cloaks are rounding up/murdering Roberts Bastards, she is there when Joffrey makes her torture the other girl on his birthday, and she even has a couple conversations with Little Finger that really help develop his character.

These by themselves don't seem like a big deal, but Game of Thrones is not a show that just throws things out there for no reason. I think that Ros will somehow have a role to play when it comes to the eventual fall of the Lannister/Kings Landing. If I missed something or overlooked a glaringly obvious detail please let me know, but I wanted to see what you guys thought

TL;DR Watch out for hookers

EDIT: I now realize she's dead. This is embarrassing.
