Well that's what I siad but there's definately a kiss in there. Might well be a 'I can't face certain death without you knowing that I still lo....ike you' suicide mission kiss but it's still there.
Seriously, is Lee still meant to be 'happily' married to Duwala (?)? Because there's no hint of spousal affection. Whether that's supposed to be because they live a frigid, sexless, 'don't touch me!' arrangement, or because the two actors hate each other, is beyond my ability to say.
But seriously, on the writers/actors part it wouldn't take any time to have dropped a few smiles here, a brief bush of a hand there. It's pretty rediculous.
