Reading Book 1 (having seen the TV series) ... any guidance on looking out for foreshadowing?

I'm currently up to the part where they've split up after Shadar Logoth and Perrin+Egwene have just met Alyas.

Only now though did I remember that foreshadowing is a thing in this series and that I may already be able to pick on the meaning of some if knowing plot points from the show, but also maybe I could be keeping a look out generally.

Without any spoilers for the rest of the story ... anyone have any guidance on whether I should keep a look out for foreshadowing and if so what sort of things I might want to look out for, especially anything that's likely to link up with seasons 1 and 2 of the show (as I'm unlikely to catch up to the show before the end of season 2)?
