Season 3, Episode 10: "The Stranded"

Ava was one of the reasons I used to like work.

She was a friend.

Now we sleep together and suddenly I don't know how to talk to her.

Every time I go to the bathroom, I pass her desk.

I have to plan little patter. I spend half my day writing.

Then afterwards I sit in my office and analyse how it went.

If it was a good conversation, I don't go to the bathroom the rest of the day.

I see her laughing and talking with other people.
