a thought: if Daeron IS wearing a wig/dyed his hair to hide his identity and is masquerading as a squire, that could be an adorable meet-cute.
Daeron has to marry to form an alliance with whatever house and he travels to the Lord, still disguised in Ormund's party. And, of course, as the pact is made and the details are discussed, not a soul thinks of the bride nor the groom, both left out of the discussion and slipping out of sight separately. Daeron is off by himself in the gardens when a young woman approaches him, asking if he is part of the Hightower's party.
"May I ask you what he is like? Prince Daeron, I mean."
"Why do you wish to know?"
"Because I am to be his bride."
This is her. This is the stranger he'll be married to and she has no clue who she's talking to...and Daeron cannot help but smile and play the role of Ben, the squire, who knows Daeron so well, talking up the prince quite a bit and teasing a little. They spend quite a lot of time together and Daeron finds that he and his lady are well suited to one another, liking her more and more by the moment. And she likes him too. He can tell that she's sweet on him, even as she gently avoids "Ben" making little flirtation here and there (which he also likes).
The Hightower's must leave to attend to some business and, when they return, she and Daeron will marry. Ben says his goodbyes and asks for a small favor, her blue ribbon for luck in the war, and assures her that she and Daeron will be quite happy together.
"Trust me, my lady, I know the prince better than most. He shall love you."
And she watches him leave, ribbon tied around his wrist, a little part of her wishing that Ben could have been more than a friend...imagine her face when he reappears later, the red from his hair gone and white curls down his shoulders, smiling at her in such a familiar way...and then she sees the ribbon tied around his wrist and figures it out, Daeron following her out to the gardens.
"You are a beastly creature!"
"And yet you love me still."
They are happy together, the two of them. And when they name thier third born son Benjen and people ask why, they simply smile.
