I have a severe wrench to add here - I intend Winter to come in contact with the press at some point, and assuming nobody has a really compelling reason to do otherwise, reveal both of her identities. While that won't directly affect anyone else on the team, it's worth noting - once you know a Precure's civilian identity, their ability to transform doesn't mean a whole lot for their identity anymore. (I know you know this, Ken, I'm just making sure everyone's on the same page.)
