Another game...it's quite simple and you can find it in many spots, so I decided to put something like it here.
You pick two things that are possible to compare, for example: Merder <--> Maddison, surgery <--> love, Izzie <--> Cristina.
When someone chooses the thing he considers better, he comes out with another pair, it can be somehow connected with the previous one.
Have fun!
Ok, starting with:

Season 2 <---> Season 5
