Needs to be updated because Meredith and Derek now have three kids, not two. Meredith now has a third bio half-sister she didn't know about it. Addison actually moves to LA at the start of the fourth season (though she visits in season three). The Harper Avery is now the Catherine Fox. Cristina's name has no H. And you really need more variations for Sofia's parents. Or make it clear that it has to be in that order
Think some of these are a bit hard to answer like who is Sofia's parents. I typed versions of that answer so many times but did you mean Arizona and Callie, mark and Callie, mark sloan and Callie torrez or all three etc. Maybe adding who are ALL of Sofia's parents would be better? And Meredith has 3 sisters and 3 kids. Also where did Derek live. I thought you meant the place not a trailer but maybe that's me being stupid haha. Maybe be clearer in the questions but still a good quiz
