James occupies a weird spot between friend and patient, sometimes, given the context of the research he was involved in, which just is what you get sometimes when you work in this field. The text comes in a few minutes later -

Gotcha. Watch out for my sister, she's been staying with me a couple months and she's still gushing about that arm of yours.

Everything okay with you and yours?

Because, yes, this isn't at all the usual time, even if it's the usual place. James, for understandable reasons, doesn't come up to the office much.
