Kramer Vs Kramer (final scene)

Yes?
It's Joanna.
I'm downstairs in the lobby.
Can you come down here
and meet me alone?
Hi.
What's up?
Tell me. What?
What's the matter?
I woke up this morning.
Kept thinking about Billy...
...and I was thinking about
him waking up in his room...
...with his little clouds
all around that I painted...
...and I thought I should have
painted clouds downtown because...
...then he would think that
he was waking up at home.
I came here to take my son home.
And I realized he already is home.
I love him very much.
I'm not gonna take him with me.
Can I go up and talk to him?
Yeah.
Why don't you go upstairs
and see him and I'll wait here.
How do I look?
Terrific.
