the comet could mean a lot of things. in the book however, its one way for us to know where everyone is at a relatively exact moment in time. the book chapters can be minutes, days, or weeks apart. so when you finish a Jon chapter and move on to a Dany chapter, it doesnt mean that chapter picks up in the same minute that the previous chapter ended.

another use of the comet was to showcase different meanings it has to everyone, but also the similarities between some of those different meanings. it could be the return of dragons that Osha says, it could be Azor Azai is reborn, and it could just be a pretty comet. they could all be right, they could all be wrong, or some mixture in between.

but heres a question, why the F would Varys try to poison Dany in S1, if they were only going to cut Aegon and have Varys support Dany in the end, anyway. that makes no sense. unless they try to get clever and act like someone else (maybe Tywin) tried to poison Dany instead of Varys. unless... this is all a ruse.
