[It's just coincidence that Ikki opens the door, really. It's not as if he has been magically managing to find reasons to wander near it waiting for her. So, yeah, it's mere coincidence that Ikki opens as soon as she knocks the door, looking at her with critical eye and a frown on his face as he steps aside to let her in. Of course she's old enough and she knows how to take care of herself and everything, but Ikki doesn't really care even if he knows he won't find unattended wounds or anything that she hasn't taken care of already, he still checks her.
She's not welcomed just by a grumpy older brother figure, though, Hyoga slips through Ikki's legs to jump at her legs with a happy bark. At least one of those two remembers and knows how to welcome someone, because Ikki, in all his greatness, is too busy eying her to say anything more than a "hn" sound.]
[Action] what do you mean, he's super polite
