It's overall cute that she finally had the ability to stand and talk for herself. It shows that she is not a total failure and actually is a real person, just not comfortable with socializing (might be related to why she doesn't care about romance anymore?)
Once again, the faces these characters — especially Momoko — pull, are hilarious!
But, tsk, yeah... Things have to feel awkward in the office, a tad bit. But, I guess they're not on the "wrong foot." So, that's good, at least.
