Dunno if its been said already but... this season, we've seen how folks 'get their news' in Westeros.
That mini-play in Braavos in a prime example, imo.
Notice: Everything in that play was
'backwards'.
- King Joffrey was portrayed as a 'kind ruler'.
- Ned Stark was portrayed as a 'cowardly idiot'.
- Cersei was portrayed as a 'devoted, loving mother' with zero malicious feelings. (until Arya told Lady Crane how she would REALLY react to Joffrey's death)
So it kinda makes sense that Rhaegar & Lynna's relationship would also get
'twisted' into Kidnapping & Rape over many years... as more & more people told the story to different people.
Just my opinion.
