Chase is dependable, in an oddly unreliable way. She's making a bigger deal of this than she needs to; worrying about the medication instead of anything else. Nothing stays hidden here, not for long, but Wilson deserves his privacy. And in a funny way, she thinks it might not hurt House to have some things kept from him. After all, the oncologist is essentially his friend's conscience; it must be uncomfortable, at least a little, being reminded of exactly how human, how fallible, he is.

"I don't think it matters, why he didn't want anyone to know." She glances at the bed now, sparing Chase any expression of disappointment. She has to admit, it is a little odd; only slightly less so in light of what she knows. But really, the nuances of Wilson's friendship with House are a mystery. It seems to be one of the few things that holds their boss together, though; and as such it's worth working to preserve.
