Well, you're asking about "caring" and "really caring" (outside the bounds of the professional relationship).

I would say all three care professionally. Loath as I am to admit it, No. 1 probably did really care; I'm going by behavior.

I seriously don't care how much any of them care so long as they do their jobs. Which Nos. 1 and 2 did, and No. 3 is doing now.
