Hugh: Don't be so hard on yourself! If someone I was in love with was taken hostage by an insane serial killer...
Jack: In love with?!?
Hugh: Yeah.
Jack: I'm not in love with Miss Fisher!
Hugh: Oh. No, no. Good!
Jack: I'm NOT!
Hugh: Yeah, me neither.
Jack: I mean, hey, y'know, I like Miss Fisher as much as the next guy. You know, clearly I have feelings for her, but feelings don't mean love!
Jack: You know, I mean, I have loving feelings for Miss Fisher, yeah! But, I have...
Jack: I have, you know, continuing feelings of love, but that doesn't mean that...
Jack: That I'm in love with her. You'know? I have... I have sexual feelings for her, but I do love her?
Jack: Oh! Oh my God! Oh my... Why didn't you TELL ME?!?
Hugh: Well, because we though you KNEW! IT'S SO OBVIOUS! That would be like, you know, telling Dot, "Hey, you know, you're adorable!"
