Its a possibility in eps 7 they link Perrin and Layla engagement to the day that Rand and Egwene get together, with Nynaeve complaining about them fighting over Egwene but then Perrin states that he never loved another woman than his wife. Would be a small step for Perrin having hid his feelings for Rand behind talking to Nynave about Egwene instead.
I would say its 50/50 for me that this is the path they are going to follow based on the first season.
