And then theres the woman who just slapped him in the face for not remembering her.
However, Sam still doesnt quite realize the severity of the situation.
(Mo money mo problems, as Dean puts it.)

But dollar bills werent the only thing in his stomach.
There was also a hex bag, which, of course, takes us back to witches.
As much as Dean loves Dory dont we all?
So, as long as Sam can keep an eye on Dean, they can hopefully fix this Mementocrap.
(And its a shame he cant remember such a great night.)
He gets as far as now salsa you mittens before he remembers that he cant read lips.
Oh, also, Dean knows how to shoot a gun?!
Yeah, its all real.
Well, they kill monsters.
Deans response: Awesome.
And did he mention that their best friends an angel?!
To quote Dean: Whaaaaaat?!
Another great (much smaller) moment?
Jensen Ackles delivery of the line, Thats a weird name when Sam mentions Rowena.
This show really does know how to have fun, doesnt it?
(Bonus points to whoever had the idea for Sam to start labeling everything with Post-It notes.)
As Dean puts it, Sucks for that guy!
As he tells Rowena afterward, Ive seen my brother die, but watching him become not him?
This might actually be worse.
Dean stands in front of the bathroom mirror reciting, My name is Dean Winchester.
Sam is my brother.
Mary Winchester is my mom.
And Cas is my best friend.
At least until he forgets even his own name.
And the moment he realizes that, the look on his face becomes one of pure panic.
Only, they also threw her out when they felt her magic wasnt up to snuff.
(Whys she willing to open up?
Because she knows hell never remember it.)
But Dean and Rowenas heart-to-heart is interrupted when Sam calls.
With that, Rowena sticks Dean in Babys passenger seat and makes her way to rescue Sam.
Only, its Dean who really ends up saving the day.
After he discovers the trunk the grenade launcher has a big NO!
Post-It on it he gets some witch-killing bullets and saves Rowenas life.
But losing the bad meant losing the good, so if thats happy, Dean will pass.
