I don't remember it all, just that the two of them wandered around aimlessly and didn't know each other. Then at the very end they finally saw each other and he said, "Let's go home". Anyone know which episode this was and how I can see it online?

Thanks!

I don't remember, but it could be episode 11 from season 1, in which there's a flash-back of how they first met in 1989.
