I have a little blip for this, for GoT Adoption? It’s when Elodie has first been taken in by King Percival into his household, but she isn’t especially accepted or well-treated. There are fears that he means to marry her to some lord to make him the heir or (gasp) make her the heir herself. She’s considered an outsider in a lot of ways, is treated as such and I feel that in that sense she becomes quite shy at first. 

But when he and Elodie pay a visit to Lady Marigold’s castle (possibly shortly before Astor begins to officially live with Percy for a little bit?) she hears the rumors about Lady Marigold’s own ward and is very curious about him. So she follows them around, ducking behind columns every time that Astor turns to look her way. Percival chuckles that she’s at a shy age, etc. Marigold talks about how Astor was once shy too – but he’s growing up to be such a confident young man. PROBABLY PATTING HIS CHEEK AS SHE SAYS THIS because she loves her boy. The adults wander a bit ahead, leaving the kids behind – Astor undoubtedly having heard the mean things said about Elodie steps out of his comfort zone, just for a second, and takes her to a beautiful room in Marigold’s home. Just to give her a moment of happiness. It makes an impression on her for a long time and obvs is the start of her crush on him.
