Now, Arianne is headed to Aegon who is currently doing well in his invasion. What if... Arianne arranges a marriage between Aegon and Mrycella?
Why Myrcella, you ask? Why not Arriane?
Because if Arriane proposes this, then Dorne is already automatically close to Aegon's camp. A political marriage with Myrcella could help turn more lords to him and give him a bit of legitimacy (a joining of the usurper's and the dragon's house would be a big shock). It could help bring more Stormlords (with whatever they have left) to join him willingly (her name IS Baratheon, after all), It could help divide or at least undermine the Westerlands (Lannister v. Lannister), AND it would be an olive branch to the houses. In other words, "It doesn't matter what you did against my family in the past, I married the offspring of the usurper and the family who brutally murdered my sister and mother. I bring peace to all who refuse to resist me."
Now Myrcella likes and trusts Arianne. So, if this happens, imagine what it would do to Cersei...
