Stefania Spampinato’s jump from Grey’s to Station 19 will start in Season 4, according to TVLine, and nothing could make more sense from a Station 19 standpoint.
Since Maya and Carina are pretty great together whenever Maya’s issues with her parents don’t rear their ugly heads, more Carina on Station 19 is probably going to be great from a relationship standpoint.
Despite her relationship with Maya hitting a major speed bump when Maya slept with Jack while struggling to deal with the situation with her dad, Carina forgave Maya after an apology (and haircut) and they were back together by the end of Season 3.
