Barbara: Headed to the meeting, after telling daisy, bruce (if he's home) Steph and Dick about it. She grabbed coffee for Tim, herself, Daisy and Tony and handed it to him, along with bringing the analysis Mainframe had done on the transmissions. Eventually they'd get to discussing it but probably not today. She's worried about their home, looking for the other Bats. There had to be a way to fix this!
Martha: Listens to the meeting topics carefully, filing most of it away and comparing it to what she knows from what she's learned. She feels a worry and a determination becuase this MUST be fixed. She has her med kit with her and is waiting for the meeting to be over so she can get Tony checked out.
Ivy: heard about the meeting and slipped in to listen. She has no experience with any of this, but this is bigger than her or any of them, and instinctively knows that this is the end of her hiatus from Security.
