That ending was unnecessarily awkward. So it was for nothing seeing that Worf got his honor back and Kurn would have gotten his.
A weird turn for a classic character.
Strange thing, before the operation, Kurn had simply passed out from being drunk. That means someone sedated and brought him to Dr. Bashir.
How did Worf convince Julian to do the procedure without Kurn's permission? Wouldn't that be considered unethical and even illegal?
And when exactly did Worf get his honor restored? He joined Martok's house, but the House of Mog was dismembered or something.
Either way, Worf made it up to almost being chancellor-if they had left Kurns character alone up until then....
