At st6, as soon as the dinner is over, and the klingons take their places on the transporter in order to return to Qo'noS wa', cheng is heard saying:

DaH machegh

I'd rather expect to hear {DaH wIchegh}. The {DaH machegh} gives me the impression of cheng saying, "now we return somewhere unspecified on something which is unspecified too"
