Welp, Crow almost got himself killed ^^;
Okay, it's not the same person, but my friend is also Filipino, so that's ironic xD
I'll write up a few of my ideas in an edit here~

EDIT: So I had a lot of different ideas, mostly on Crow's end but some that would affect Penelope too
1. He would have to start going by his real name, because "no self-respecting ambassador can be named after a bird" (It would be a condition his father sets in order for him to take the job).
2. There would be a lot of conflict between him and his brother, Braden, because Braden would be afraid he's after the throne, even though he doesn't want anything to do with it.
3. Crow would have to stay in the castle to be tutored, since he's uneducated and illiterate. He would hate this and probably sneak out a lot to get away from it
4. Shenanigans with Naida (if Penelope is around at the time, I could see all three of them being involved in this)
5. Kind of a bigger plot idea, but what if Albin sends Crow to Younis to try to negotiate with the king (it's now the son of the last king, who died about a year after Crow and Penelope had left before). While he's there, the Younisian king's oldest daughter takes an interest in him, so the king writes to Albin that he's willing to settle on setting up an arranged marriage between them to end the feuding between Younis and Brerra. Of course, Crow would be completely repulsed by the idea because he wants to be with Penelope (she was the entire reason why he accepted the job offer in the first place), so it would cause some interesting conflict between him and his father. Also I could see Albin accepting the proposal without talking to him about it first, so the Younisian king would send his daughter to the Brerratic castle to be formally courted and there would be a lot of tension between her, Crow, and Penelope if she's around at the time.
I think the last one really depends on what happens with the war
