Again, I feel like this is so random....
First, why is he nervous? He did nothing wrong?
Second, we've seen almost nothing of their relationship and now they show us this as if we're supposed to care about their relationship when we know nothing about it...
Third, if their relationship is as good as they made it same in the very small things they showed, why is she reacting like this over him having contact with a women? Are you gonna be that kind of partner, that doesn't wait for your partner to tell how things went and just questions his loyalty from what she heard when he was in an official meeting with the king?
I feel like this story has been ruined as it's no longar about how he grows and changes as a character... He's made no improvement over the investigation on his father, he's relationship with the fire tower master and with his fellow mages is hardly ever shown now. It's like from some point in the story, they decided that the story's pace would be really quick and with no details... I feel like I'm watching one of those shitty summaries of a story on youtube... This could have been so much better...
Also it makes no sense that a spirit that takes the form of a dragon inherits the power of an actual dragon and, from what I've seen, also becomes a dragon, they are two different species... Spirits don't have fisical bodies, they are maintained in "our world" with the summoner's power. While dragons are beings way more powerful than even humans and their magic normally originates from the heart. I mean, I know this is all knowledge we invented, and spirits and dragons don't exist, which is a shame, but you have to make sense, spirits and dragons are always thought of as very different species, so this makes no sense and to make sense they would have to explain how that would work because to me it doesn't...
