After telling everybody the truth about babies.
THOR
Men and women really do that kind of… stuff?
SIF
That's... disgusting.
FANDRAL
That means I'm not a father of two thousands children?
VOLSTAGG
What a relief!
HOGUN
...
ME
I know it's a shock to all of you. But I promise it can be very enjoyable.
FRIGGA
Although it takes some time.
THOR
Father, do you and mother...
ODIN
Don't think about that!
THOR
... I'm sorry... But now… Knowing that… I can't look at you with the same eyes.
VOLSTAGG
For the first time of my life I lost my appetite.
SIF
That's so disgusting. Oh, I can't get that image out of my head.
VOLSTAGG
I have to throw up.
ODIN
You see what you have done, mortal? It's better to be clueless to such trivial things. Fortunately, I know a spell to erase their memories.
ODIN casts the spell. The only ones who remember the conversation ever happened are ODIN, FRIGGA and ME.
