Carol and Doug SPOILER.
These two had such great chemistry, but I'm a bit miffed about Carol's exit.
They were apparently so in love, then Doug moves to another city, doesn't do anything to support her after finding out she's pregnant, doesn't visit when the twins are born. Doesn't help her out at all. Then she decides she she still loves him and that's that, they live happily ever after in settle.
I just didn't think the ending fit her character.
