Jack and Gwen in “Dead of Night”

Jack

I was thinking. About how you're immortal. And I'm dying. And what I wanted to say was... we're good aren't we? You and I? Good team. I missed you.

Gwen

I was thinking that, ah, if this had happened a bit sooner...

Jack

I know.

Gwen

He'd still be here, Ianto.

Jack

Dead friends.

Gwen

I'm sorry.

Jack

I wish he was here now. Not much of a team, is it? But we've still got each other. You and me. Just like the old days.
