Moonspear wanted to let you know

It was clear that it mattered a lot to Flóki, this. In a way this reminded Charon of Levi; while Charon had no twin brother of his own, he remembered the incredible impact that Kevlyn's absence had had on Levi's life. Perhaps that was part of the reason that Charon despised Jorunn so, blaming him for what he had done to Flóki, even if it was not willingly. An irrational thought, perhaps, but the drive to protect those close to him was strong within Charon.

The silence in which Flóki processed his thoughts and feelings on the matter was broken by another question altogether. Charon had always gone by Ostrega because of two reasons; the first the unspoken bond he and Levi had shared, an honour to his deceased mother, who'd died for them, of sorts. The second that it had never occurred to him to use the name of his adoptive parents.

The question therefore came as a surprise to Charon, and it was clear on his face that he hadn't been prepared for it. But the answer was surprisingly nearby for how unprepared he was: "Yes, of course! I mean, I haven't ever put super much stock in the name, but it's what reminds me of the sacrifices my birth parents made, so... Yes, of course." Adding Flóki to the "Ostrega" family only made its meaning stronger, if anything.
