Marlene would've been quieter than usual (at least at the start of the meeting), since she's still very heavily medicated and physically still beat up some since her run-in with Quentin on Sunday. Most of her time was spent curled up on what was probably a very sleepy two-days-post-moon Remus, although she would've congratulated Doc and Meg and given Ted a hug since she hadn't seen him since the Ministry was attacked. She would've mentioned the same stuff that she blogged about here for anyone who missed it, because YAY THEY HAVE SOMETHING GOOD AND HELPFUL and everyone in the Order should know about it because it shows that they can still do something even post the takeover.
She would've mentioned that she definitely wants to do another radio show soon, and would've asked both if anyone wanted to help out with that, and also what things people think they should cover this time.
She also would've sighed and suggested they "start singing kumbayah outside of ice cream shops again" out of frustration, "although apparently that doesn't work."
