As he wagged his finger at her, Elphaba gave him a salute in response. "Yes, sir. No giving up. Got it." And well, wasn't that something she'd learned since being in this place? That anything could happen at any given time? And not to mention, the Seal had sent Elena home once and it had brought her back. Perhaps it would do the same with Galinda at some point.
"Perhaps you might be, but I don't mind." Rather she wasn't used to being thanked in such a manner. Yes her friends had said as much when she'd helped them, but everyone else? Not so much.
When he extended his hand, she reached out and shook it, returning his smile. "I am glad I was able to be of help. And a less stressful arrival is most certainly a good thing. I hope you settle in all right. I know it can take a little while to properly digest it all."
