Honestly because I feel like Reagan and Gigi were the only two women in the office (and lowkey the most competent ones) that they always kind of wanted to be friends but just never approached each-other because they assumed they didn’t like eachother. Even in season 1! When everyone is bitching on Reagan about how she looks (tired) Gigi always makes sure to ask her if she’s okay in a follow-up

And they never shit on each others work either! Their work is very different with Gigi manipulating the media and having to keep up with current news and everything, and Reagan being a scientist and co leader of the team. They have never acted like the other is beneath them (ok maybe Reagan did in early season 1 but she just did that to everyone). They do little projects for eachother (Reagan making Gigi a robot for the news, Gigi helping Reagan with the Keanu drama)

And in season 2, Gigi never tells Reagan to stop asking her about Ron or getting her help with her life drama and Reagan makes sure that Gigi knows she finds her work really cool! because well now they’re spending time together and it’s a bit tentative but it’s also a solidarity they’ve both been needing for a while.
