Well i thought season 3 was very interesting because we get to know the character better and as always the comedy/drama/action was very balanced not many show can balance this but this show does but i love how they deal with relationships in this show and how things never are so easy but as always no matter what we have not lost any character i really thought after izzy cut danny wire she wouldn't return but she did, you just know that would never happend in real-life 8million dollors she could spend it have wonderful life but instead she comes back to settle grey's. i just don't get that but maybe that's just me .
Meredith and Derek-i'm really surprised how strong there relationship is no matter what these two will last
Addison and Derek-i felt bad addison she tried to make it work but no luck i'm glad she realised that decided to move on.
Addison and Mark-that was just one-night stand but mark did the right thing and walked away finally he does something decent once
Callie and George-ok i never really thought these two would ever last they got married and i just couldn't believe it.
Izzie and George- this came out of the blue and it was brilliant, i really do hope things work out and you can clearly see how their relationship changed half-way through the season. i hope they do last
Cristina and Burke-now this was awful to watch i love how burke tried his best make her happy and he realised at the end she didn't really want to get married so he made it easy and walk away now news about him being fired means they find new surgeon to replace him for season 4. i'm going to be sad to see him go because i really liked him.
