Claudia is the type to organize and open her space for the meetings -- sometimes it's literally just members of the community coming together to discuss, raise awareness, organize themselves for fundraisers/protests/marches/etc., make signs, call lawmakers, fill out postcards, etc. but sometimes she'll have a speaker. She wouldn't speak herself, she'd prefer to invite other speakers to give them a platform to use their voice, so maybe Chantal has spoken at a few of the meetings (if she's into that?) and they've struck up a relationship through that?
