"It's quite alright. I was already seperated from my friends for quite a while back home, so nothing much has changed for me."

Inigo makes sure to say it as lightly as possible. Does he actually miss his friends? Of course. And he misses his own sister even more. (So, knowing that feeling, he feels glad for Nita that she can actually have her own sister here with her.) He was a mess during the time they were seperated back home as well, after all. But his own sad feelings aren't something he needs to burden Nita with. He may have gotten a little better at sharing some of them, but this feels like something he can bear by himself still.

"Besides, it's not as if I'm here alone. I'm fine with just hanging around with all of you I've met here. It's kind of hard to feel lonely with a friend as great as you, you know?"
