As she'd been next door, it seems easier to wander over and see the new place for herself. Natasha had known that Darcy had been up to something in the rooms next door although she'd left the girl to her own devices for the most part, since the keeping busy seemed to help her mood and stepping in now, she lets her impressed expression show her thoughts on the matter.

"I wondered what you were doing over here. my, you have been busy, haven't you? It looks great, Darcy. I'm impressed."

It actually reminds her of the place she'd taken the girl's Mirror when she'd found her here and found that an odd little coincidence.
