For now, Ginko guesses he might as well assume it's both. So he stays where he's sitting, watching Yukio carefully, trying to work out whatever he can of his condition. Besides... generally bad.

"...Well, if you do need anything else, let me know. That includes if you want to talk - or to be left alone."

The last suggestion takes some effort to get out. He doesn't want to leave Yukio alone. He doesn't want to leave him to die - but if he won't talk, he won't, and there's nothing Ginko can do to force him.
