Mind = blown.
That was insane. Such a great episode. Am completely snatched.
But what if Anna gave birth to Wes, gave him up for adoption because she wasn't ready or some **** and then never went back for him.
And then she started missing him, got into an argument with his other mother because she wanted him back, did something bad which ends up in her being dead?
I think the whole "Annaliese his his mom" is way too obvious, I don't think Shonda would go down an easy route like that.
