Even if it's been a while, after fighting blindfolded for more than a year Riku doesn't need any light to guide him to his enemy – but for all that he's prepared to battle the intruder without sight… he isn't quite prepared for what actually happens.

He hadn't thought that his enemy wouldn't put up a fight at all.

Riku frowns to himself, especially when an all too familiar voice hisses in pain, then calls out – and now he's finally awake enough to recognize the scent that's entered, wonders how he's not sensed it before (a light as bright as Sora's, the faint taste of sea salt and nothingness on his tongue that he associates with Nobodies… so yea, there's no doubt on his mind that this is…)

"Roxas!?"

What in the light… and speaking off, it's probably a good idea to stop standing around in the dark, especially since there apparently isn't any enemy to face after all probably, so Riku mutters:

"Lights."

Sure enough, the lights in his room flicker into being at voice command, revealing the curious image of Riku in his sleeping cloths holding Way To The Dawn while blinking to get used to the sudden brightness, that reveals what his other senses already told him – Roxas, combat ready and holding Oathkeeper. The image brings Riku to a million questions – most of which he can answer himself a second later, so finally he settles for:

"Why did you open a corridor to my room?"

Like really. What reaction was he expecting to happen? Or is this just the natural evolution of Sora's habit never to knock?
