Just watched it, and I agree TizzyDongue, it was exhausting waiting for Jack to come to an unfortunate end!
Me and himself have had one or two fights like that over the last 20 years, and they have usually been resolved after a day of sulking, a bit of a chat, mutual apologies and a shag! No separation required.
Mind you, if my DH ever made a speech like Jack did I think I would die of shock!
When is series 2 starting?
