[While this person looks like Vash normally does. It is in fact his core. Most of his lies have been stripped away for the moment. They being the distractions that lay outside this chamber.]

I was tired. [He exits the safety of the glass, it melting around him and once he steps out it reforms again into solid glass.] And it can be safer for others. If I stay here and quiet. I don't want anyone else to get hurt. [It remains unsaid, but he doesn't want to be alone either. It's why all the doors are unlocked and why he won't sleep forever.] If you were looking the way out. I can show you the way.

[As for Cole being dangerous as well; he hasn't learned enough of him just yet to make a full decision. Vash doesn't doubt that Cole has the power to be dangerous so he won't deny it, but he won't confirm it at this point either.] You are very considerate. I don't feel that I'm in danger around you. [Unsettled at times? Yes. In danger. No.]
